Tip 1

The next factor is age-related changes. Over the years, the retina ages, the photosensitive pigment is gradually destroyed, and visual acuity deteriorates. Drying of the mucous membranes of the eyes is another common cause of disruption of the visual system, especially for people whose work involves working at a computer. Due to the increased concentration of attention on the monitor, the person begins to blink less often, as a result, there is dryness in the eyes. In general, the frequent use of gadgets has a negative impact on vision, since the eye muscles systematically perceive information at the same level, as a result of which they lose their shape.

In addition to the above, visual impairment may be a consequence of past diseases, such as diabetes mellitus or hypertension, oncological diseases of the brain, as well as stress.

Tip 2
If a person has noticed that the quality of vision has changed dramatically, it is necessary to immediately contact an ophthalmologist, as well as a therapist. Specialists will conduct a special ophthalmologic examination and will give directions for delivery of tests – general and biochemical blood tests, brain MRI, vascular examinations and other examinations that will help determine the cause of this symptom and prescribe timely treatment.

Tip 3
If the cause of visual impairment is frequent stress or an abnormal diet, in which the body is not fully saturated with necessary vitamins and minerals, a person can restore it on their own.

It should be less nervous, and also give your eyes the opportunity to relax, reduce the time spent in front of the computer screen, TV or phone. It will not be superfluous to devote a few minutes to special eye gymnastics every day. Spend more time outdoors. Include foods rich in vitamins A, E, and C, lutein, and omega-3 in your diet. Carrots, blueberries, spinach and seafood are especially useful for disorders of the visual function. If it is not possible to obtain a sufficient amount of useful macro- and microelements from food products, it is advisable to use vitamin complexes.

Tip 4
Performing special exercises can help partially restore vision. Close and open your eyes tightly several times, look in different directions without turning your head, close your eyes and repeat all the same exercises. Consider the room in which you are located, or several objects that are near and far from you, look out the window.

Systematically perform these exercises several times a day, then you will notice an improvement in the quality of vision and unpleasant symptoms will disappear.

Sometimes the lack of certain nutrients for the eyes can lead to certain problems with vision. Inclusion of food products containing essential components for eye health will improve the functions of the visual analyzer.

First food: green peas

In green peas there is a large amount of lutein pigment, which is responsible for visual acuity and color recognition. The body receives lutein from certain foods, which then accumulates in the retina of the eye. And the denser the layer of lutein, the better the color perception and vigilance.

A hundred grams of green peas contain about one and a half milligrams of lutein. In this case, the daily requirement of the body in lutein is about two milligrams. Green peas can be added as an ingredient in the various dishes: salads, soups, as a side dish to second courses, etc. It is enough to include a hundred and fifty grams of green peas per week in food. Since lutein is a fat-soluble substance, it is necessary to add a small amount of vegetable fat to the dishes.

Second product: onion

Onions contain a lot of quercetin, as well as ascorbic acid, beta-carotene and other vitamins and trace elements. Quercetin increases the permeability of eye tissues to beneficial substances, which improves the nutrition of the eyeball and helps the body to recover more quickly after hard work.

It is recommended to add a bulb onion of medium size to daily nutrition. It can be used in any form and includes the composition of various dishes. Even after heat treatment, useful substances remain in it.

Third food: fish

To improve the circulation of tissue fluids in the eyeball, as well as in all surrounding shells, it is useful to regularly eat fatty varieties of sea fish.

In oily fish contains a large number of polyunsaturated fatty acids omega-three (PUFA), which improve microcirculatory processes in the body, including in the eyeball. Fish can be consumed, both in a boiled form, and slightly salted. Enough to include in the diet at least one hundred and fifty grams of fatty fish several times a week.

Fourth product: nuts

Collagen fibers support the lens in its normal state. And vitamin E provides protection of elastic collagen fibers. Enriched with vitamin E nuts and some other foods. To make up the stock of tocopherol enough to eat every day a handful of nuts (twenty to thirty grams).

The fifth product against niktalopiya: eggs

Some people begin to see worse at the time of day. This condition can be as innate (inherited from parents to children), and acquired, it often arises from the lack of necessary substances for the eyes.

To avoid the appearance of night blindness and to see normally in twilight, eyes need an element such as zinc, as well as vitamin A. In the yolk of chicken eggs, there are two of these components. The egg protein promotes normal absorption in the body of these elements. You can eat one egg every day or a couple of eggs every two days. And it is desirable to eat soft-boiled eggs or to cook an omelette.

Are the eyes tired?

As is known, every day the human eye is exposed to various negative factors. Especially the load on the visual apparatus has increased in our time. Accumulating with every day the fatigue of the eyes can lead to certain problems with vision and eye diseases. Determine if the eyes are tired, the next test of five questions will help.

Test for eye strain

1. Do you have after appearing after reading or working at the computer, flies in your eyes, dark spots?
2. Are you suffering from headaches after a long reading or working at a computer?
3. Do you feel heaviness in the ages after reading or working at a computer?
   Are you irritable after working with small parts, reading or using a computer?
4. Do you lose your appetite after reading or working at a computer?

If you give a negative answer to all the questions, this indicates that the risk of any problems associated with eye strain is minimized.

A positive answer to one, two or three questions indicates some problems. Timely assistance to the eyes will help restore vision back to normal.

Those who regularly have four or all five of the above symptoms are likely to have serious problems and need to seek help from an ophthalmologist.

Exercises for prevention

To remove the eye fatigue that has appeared for a day, you can do special exercises. Performing gymnastics takes a total of ten to fifteen minutes a day and will help not only to eliminate fatigue in the eyes, but also to prevent against this background the fall of vision. It is recommended to do such exercises twice a day: morning and evening.

Warm up: you need to sit up straight, straighten your shoulders, relax. The tips of the index, middle and ring fingers should be massaging movements in the cervical vertebrae for three minutes, moving from top to bottom. Such a massage will improve the blood filling of the eyeball and prepare the eyes for exercises.

The first exercise.

Looking forward, blink quickly for thirty seconds.

The second exercise.

My eyes are closed. Make light short-term (one to two seconds) pressing on the eyeballs folded together with three fingers. Exercise is carried out within two minutes.

The third exercise.

Pull out your right hand in front of you and lift your thumb up. Look at the tip of the thumb with two eyes for five seconds. Then close your left eye and focus your eyes on the tip of your finger with your right eye, then change your eyes. Do three or four approach exercises.

The fourth exercise.

Label on the window. Using a felt-tip pen, make a small mark on the window and stand in front of it at arm’s length. Look at the label for five seconds, and then focus your eyes on any point outside the window, which is at least five meters away from the eye. Repeat the exercise ten times.

Fifth exercise.

Close your eyes tightly for thirty seconds, then relax.

Performing gymnastics takes literally five to seven minutes. After the exercises, there is relief in the eyes, and they are ready for further productive work.

Proper food and appropriate eye training through exercise will be an effective prevention and will help keep the vision sharp for years to come.

Reading is also a very serious strain on the eyes and brain of a person. Can we “read” correctly? What is the right habit of seeing?
Several simple rules-habits will help you maintain eye health, high performance and a good mood.

 1. Have a rest every 40-50 minutes of reading and other visual work.
This rule can be called the basic rule of good vision, which applies to all kinds of loads on the eyes. In the process of perception of the text, the brain passes through three stages: adjustment, preparation for assimilation, active, qualitative perception, and then, after 30-40 minutes, there is a decline in attention. There is only an extra burden on the eyes, continuing to conscientiously perform their work for nothing. Rest for 5-10 minutes and with new forces continue reading or your studies. The practice of changing or resting with visual and mental loads is best kept for life.

 2. Periodically change the distance from the eyes to the text.
Long reading or writing at the same distance leads to unnecessary tension, constriction, spasm of the eye muscles. Eyes lose the ability to refocus and, accordingly, the ability to clearly see the images in the distance. Develop a habit of swaying in any direction while reading and moving the book in your hands to the various distances available to your eyes. Do not forget about the need to maintain a straight line between the back of the head and the backbone.

3. After reading each paragraph, look to the side.
This recommendation is like a continuation of the previous rule, which teaches us to change distances. Only here it happens by a simple and frequent look to the side  of the various objects that are in sight. Initially, consciously tearing your eyes from the text, you can then refocus automatically. If the text has very long paragraphs, throw the view into the distance every 4-5 sentences. Choose as objects of attention some pictures, a picture on the curtains, a statuette or a flower, it is better that only beautiful views can be seen in your eyes.

4. Blink easily and often, first at each point.
Moisturizing and protecting the eyes, blinking allows us to get a tiny but breathing space. From each point for a couple of hours of reading, there is already a decent rest for the eyes, and this does not affect the quality of perception and reading speed. But the eyes are just much less tired and much more will serve you.

These little tricks will help you and your child not to overwork while reading or preparing lessons, and most importantly they will help to keep eyesight for many years.

Acquired by myopia suffer primarily IT people, accountants and financiers, whose work is inextricably linked with hours of work with gadgets. Why is this happening and how to protect your eyesight?

When a person spends a lot of time at the computer, his eyes are in constant tension. The muscles that are responsible for changing the curvature of the lens and for seeing at a close distance are normally much higher than those that straighten the lens and allow seeing distant objects. But if a person does not do the proper breaks in work and does not relax the eye muscles responsible for “close vision”, then in time to relax them becomes incredibly difficult, if not impossible. This is the acquired near-sightedness.

In order not to spoil your eyesight, a person is obliged to take breaks in work, not to sit near the monitor for days on end, and even for days and must perform special gymnastics for the eyes. It will help, if it is a question of the initial stage of the disease, and if the disease is started, then the doctor together with the patient can only achieve that myopia does not progress. Therefore, it is better not to start the disease, and if you have to work long hours with a computer, you need to find time for charging for the eyes.

These exercises are necessary to relax the muscles of the eyes, relieve visual fatigue and prevent the onset of myopia, and also to prevent its progression. This charge can be performed both at work and at home.

Try to blink your eyes very often for one or two minutes. Do not strain your eyelids.

Close the eyelids tightly for 3-5 seconds, and then open for the same time. Try to repeat at least seven times.

Drive your eyes in different directions: you can draw circles, eight, conduct a visual line from the bottom up and from top to bottom. This can be done with both open and closed eyes. If the eyes are open, stop looking at the surrounding objects: a table, a vase, a book, and so on.

The three fingers of the right and then the left hand, easily press on the upper eyelid of one, and then the other eye. Hold for 1-2 seconds and remove your fingers from the eyelids. Repeat several times.

Go to the window. Choose any point near you, for example, a speck on the glass, focus on it, and then look at the distant object, for example, the top of the tree of the neighboring yard. So translate your eyes from a close point to a distant one.

For this exercise, the head should be fixed. Raise the half-bent right arm up. Slowly lower your finger from the top down and lift it up again, while watching it with your eyes, without moving your head. Repeat 10 times.

For this exercise, the head should be fixed. With a half-bent hand, slowly drive from right to left and back in front of your eyes, while watching with your finger your finger. Repeat at least 10 times.

Why do eyelids twitch

Visual overwork. One of the most common causes of eyelid twitching is eye fatigue. Many hours spent for uninteresting, but necessary work in front of the computer screen, the habit of reading in transport, the lack of night rest cause overstrain of the muscles around the eyelids.

Nervous overload. Eyelids twitch with considerable nervous overload, when the psyche is in constant tension for a long time, is stressed. The nervous tic near the eyes can begin after receiving unpleasant news.

Neurosis. The reason why the lower or upper eyelid twitches, may be a neurosis. What to do in this case? Try to find what is traumatic – that inner conflict or circumstances that caused stress, the source of emotional or intellectual overstrain of the psyche.

In some cases it helps to think carefully, to rethink the situation, to draw the right conclusions from it, to be ready to exclude the factor of its unexpected repetition in the future. It is necessary to relax in one way or another, to calm down, to give the body rest.

Conjunctivitis. In a number of cases, eye twitching is associated with irritation or inflammation of their mucous membrane – conjunctiva. From a prolonged overexertion of the organ of vision, or for other reasons, it seems that sand has got into your eyes, you always want to blink or squint to remove discomfort and see better.

In this case, it is worth turning to the oculist who will prescribe the treatment of conjunctivitis, because otherwise getting rid of blurred vision with the help of eye twitching, frequent blinking, squinting can become a habit that will make it more difficult to get rid of a nervous tic and worsen visual acuity.

Eye diseases. If the conjunctiva is OK – the eyelids are not itchy, the color of the mucous is pink, but the vision is not clear, especially towards evening, especially it is worth turning to the oculist, in order to find out the cause as soon as possible, why eyes are straining and jerking, vision deteriorates.

Hereditary factor. In some cases, the jerking of the lower or upper eyelids can be inherited from the parents who suffered in due time.

Weakened immunity. The nervous tic, twitching near the eyes happens with weakened immunity, after recently transferred infectious diseases, acute respiratory viral infection, acute respiratory disease.

Nervous disorders. In serious cases, the lower or upper eyelid twitches with this or that disorder of the nervous system. Increased neuro-reflex excitability, convulsions begin, muscle hypertension. Against the background of these violations appears jerking near the eyes.

Violation of cerebral circulation. The twitching of the eyelid can indicate a disorder of cerebral circulation, high blood pressure. In this case, it is worth turning to a neurologist, undergoing magnetic resonance imaging (MRI).

With prolonged nervous tics of the eyelids, jerking of the eyes, it is necessary to consult a doctor.

What to do if the eyelids twitch

To remove the accumulated muscular tension around the organ of vision, and also to relax the psyche, to lower the stress on the body, it is necessary to give him periodic rest with the help of palming:

• Sit on a chair so that the back and the back of the head form a straight line. This position helps maintain optimal blood flow to the brain.
• Several times shake your wrists to relax the tension of the psyche through their relaxation.
• Rub palms on each other so that they become warm.
• Place the elbows of both hands on the table. Palms and closed fingers folded in the form of a handful.
• Palms to attach to the eye sockets so that the closed eyes are opposite the recesses in the palms.
• The nearest phalanxes of little fingers to the palm of your hand are crossed on the bridge of your nose like arches of glasses.
• The rest of the fingers, except for the large ones, arrange the forehead. The thumbs are pressed against the brushes.
• The bases of the palms near the wrists are placed on the cheekbones.

The palms do not fit too tightly, the eyelids should be able to blink freely. But through the places of contact between the palms and the eye sockets, there should not be light. Brushes are not tense, they only support the necessary tone.

With closed eyes, you need to imagine something pleasant that does not relate to the current production task or a tormenting problem. It is best to imagine something pleasant, which gives pleasure or a smile.

Exercise to relax the psyche and rest the organ of vision must be done whenever there are signs of fatigue or the eyelids twitching. The duration and frequency of execution depends on the availability of free time.

Factors forming the first impression

The process, during which the impression is created, lasts only a few first minutes when meeting. Despite this, it fits in people’s minds as a guide in building future relationships. The way a person is perceived at this moment depends on many factors that influence the formation of the first impression. Most modern psychologists are trying to make a list of the most important points, which are addressed first.

Today among them there are:

External appearance. This factor can be explained as an estimate of the overall picture. These are emotions that arise for the first time when a given person is seen. They are not backed by conversations or manners, but are simply built on the feelings that it gives to his appearance during the meeting.

Elements of appearance. No matter how one tries to object, the most important point in shaping the first impression of a person is the evaluation of material qualities. This clothing, and the state of hair, nails, skin. All that can be seen with the naked eye even before the conversation. Absolutely all people pay attention to this and take note long before the recognition of a particular person as a person.

Manifestation of emotions. Only after evaluating the previous qualities are the intangible characteristics of a person taken into consideration. At this point, attention is drawn to the manifestation of feelings. It is important how this person behaves in this or that situation, whether he will smile during jokes and what views on life he shares. Thus, assess the moral qualities, which is also important in acquaintance.

Features of behavior. Many people are able from the first minutes of the human position to determine many of the features of his character. To do this, they assess the gait, the position of hands and feet in communication, gestures, movements of facial muscles and even the nature of a smile. These and many other points allow us to determine the intentions and openness of the opponent, his habits and attitude to the company. This point is extremely important also because it helps to know the type of person’s character.

Individual qualities. The last thing that is assessed when meeting a person, are his personal characteristics. These are the qualities that distinguish it from the general mass. These can be both views on life, and the presence of a birthmark on the chin. In a word, what can attract and attract the attention of those present.

Most often these factors are used in this order. But, despite this, every person has a tendency to notice what is more important and interesting, changing this sequence.

Distorting first impression effects

Given that the first impression of a person is formed in an incredibly short period of time, it can not be called objective. The thing is that its formation is influenced not only by this moment, but also by other factors. These are various circumstances and information that can distort the resulting picture. Often happens so that when an individual sees his opponent, he already has certain subconscious prejudices on his account.

There are several effects that have this effect:

Halo. This concept means an exaggeration of the significance of the first impression. After all, it can create a certain image that will be taken into account in all subsequent meetings. For example, if, at the first acquaintance with a woman, a man likes and becomes interested, all her bad deeds later she will justify herself. Exactly the same situation can arise and not in his favor. If he was late or unsuccessfully joked on the first date, then hoping for the second does not make sense.

Primacy. When assessing a person, everyone is inclined to set their priorities. And so someone first looks at the color of the eyes, while others look at neatness in clothing or generosity. It is the impression from the first point that can determine the attitude towards this person in general. Therefore, someone can be subdued by a beautiful jacket or by saying the desired phrase, even if, in addition, a person can no longer boast of anything. Perception forms what was originally presented.

Boomerang. Almost every person knows what this phenomenon means. The thing is that people are always inclined to somehow counteract the influence on them. Therefore, in relation to those who immediately tries to join the team, draw attention or put themselves above the rest, negative emotions are developed. Everyone perceives them as enemies, and, despite subsequent acts, everywhere they look for a dirty trick.

Condescension. This attribute is exclusively a feature of a person who has to make up his mind about someone. There are people who are inclined to feel sorry for others, so they will all be initially well-behaved. Their opinion can not be called objective, but this is how they see others.

Stereotype. A very common phenomenon that occurs in relations between men and women. It is in such cases that people tend to perceive new acquaintances already with a preconceived bad opinion. If the lady was once changed, then every subsequent male representative will need to prove to her that he is not like that. And it does not matter at all that she has no reason to think so, because the stereotype that has prevailed here before.

Projection. This happens among people who really do not like any qualities in themselves. That is why they subconsciously try to discern them in others. Therefore, the opinion of a person will be inherently bad, because it is backed by the most unloved habit or character trait. People rarely see these problems themselves, but communication with them is still quite difficult.
How to make a good impression

For the construction of any relationship, it is very important that a person is recognized from the good side. Not all people are able to show all their advantages, and this is quite capable of alienating others from them. To learn how to make a first impression, there is absolutely no need to reread millions of smart books and monographs. It’s worth just letting yourself be yourself and taking into account some facts about your opponent.

Features of the behavior when meeting

First you need to gather your thoughts and set a goal for this meeting. It is necessary to clearly understand how important it is for a person that they think about him. Having found out for yourself these criteria, you can start preparing yourself.

Here are some tips to keep in mind when meeting:

Be natural. When a person has an important meeting, he tries to prepare for it as carefully as possible. But outwardly such ideality may seem faked and unreal, which will alienate you even more. Moreover, all acquaintance will be spent on reflection, so that something does not forget and do not say too much. Therefore, such a long preparation will not lead to anything good. It’s better to be yourself and to communicate with a person sincerely, without unnecessary fuss.

Do not flatter. In order to please someone, it’s not necessary to imitate him completely. All people are individual in their actions and views. And the presence of one’s own opinion is more to the liking of sneaking and conciliation with everything. Of course, it is not necessary and too fiercely to defend your point of view, so as not to offend the opponent. Everything should be in moderation.

Enjoy the meeting. Despite what people will be present during the conversation, you need to calm yourself and come to this situation wisely. If the meeting does take place, it is better not to oppose it, but, on the contrary, to look for points of contact with the person. We need to listen carefully and take useful information for ourselves. Such a meeting can bring many benefits to both sides in constructing a constructive approach.

Look at yourself from the side. Sometimes this skill helps a person to make life easier during important meetings. After all, we look at ourselves from a completely different angle. Gestures and jokes of the individual can be understood only to him alone, but outsiders are able to perceive them as an insult. Therefore, it is worth reviewing your manners in communication so that they are accessible and understandable to everyone.

Identify your advantages. To interest someone, you must first determine for yourself how this can be done. After this, it will be much easier to establish communication, because a person will know their main virtues. They should draw attention from outside and make communication interesting. Such attractive moments can serve as a sense of humor, friendliness. If a person can not understand what interesting he has to offer, you must carefully work on yourself.

Rules of Conversation with the Interlocutor

• First, your opponent must always be recognized as close as possible, and will learn to understand his interests and views on life. This will help to construct a conversation more constructively without embarrassing moments.
• Secondly, it is necessary to adhere to universal rules of conversation, which are universally recognized:
• To listen. This is required by each interlocutor. Everyone is very important and necessary that they are paid attention, showed tolerance and nodded their head in response to some phrases. If such an opportunity was provided, then in the future the conversation will be very productive. At least, out of a sense of courtesy, a person will not be refused requests, they will be called a good listener and interlocutor.
• Do not talk much. It is very important that the opponent does not feel himself to be unnecessary at the time of the original monologue. People who start a conversation with the discussions of their problems, only frighten off themselves. Do not bother his companion with excessive attention and chatter. Any conversation should end before a person begins to hint about it or speak directly.
• To address by name. For some reason, few people remember this point in the modern world. But in fact, any person is always pleased to hear his name. Therefore, you should try to do this as often as possible. Thus, respect for the interlocutor is manifested, and the first impression of his opponent also improves. Naturally, this does not apply to business meetings, where it is necessary to address by name and patronymic.
• Make eye contact. However strange it might sound, the method does work. A direct look in the eyes suggests that this person is really important to his interlocutor. The maneuver will definitely be appreciated.

Our eyes are an open window into a bright world full of joyful colors and magnificent in its beauty phenomena. With the help of our bodies of sight, we perceive more than 80% of information. However, constant work at the computer, reading in the dim light of a lamp or in transport, improper nutrition, insufficient sleep and a deteriorating ecological situation are causing irreparable harm to the eyes. The problems of accommodation are only exacerbated, leading to retinal dystrophy. Stress and smoking, which drain healthy tissues, can also cause some eye diseases.

HOW TO SAVE EYE HEALTH?

Statistics show that 75% of the population of our planet have some problems with the eyes. However, not everyone remembers that most of the troubles associated with visual impairment could be avoided. But in order to preserve the health of the eye, it is enough to observe only a few simple rules.

Use sunglasses. UV rays are getting stronger every year, adversely affecting the health of the eyes. Solar radiation can cause damage to the cornea, as well as accelerate the development of macular degeneration and cataracts. The sun is especially dangerous for those who are forced to spend their entire day on the street, who have already had one or more surgeries for cataract removal, for those who take a number of medications that can increase the sensitivity of the eyes to bright sunlight. Really high-quality sunglasses can hold UV rays of type A and B, reduce the brightness of the glare and increase the clarity of the image.

Refuse bad habits. It has been scientifically proven that tobacco consumption negatively affects the health of the eyes. This habit leads to cataracts and is able to significantly increase the risks of macular degeneration. In addition, it is also worth remembering that the body of a person who smokes is not able to properly absorb all the vitamins and trace elements needed by the eyes. From their lack, the optic nerve is depleted, and vision gradually begins to deteriorate. Alcohol contributes to dehydration of the body, including the eye. Therefore, if you drink alcohol regularly, then you have a high risk of dry eye syndrome.

Monitor the blood glucose level. Continuous consumption of animal fats and foods rich in glucose in food can lead to severe sugar surges in the blood. In turn, this provokes the development of type 2 diabetes. Often, this pathology is accompanied by such eye diseases in humans as diabetic retinopathy, cataracts and glaucoma. A sharp increase in blood glucose levels can also cause changes in the structure of the lens, which lead to a decrease in vision.

Keep blood pressure and cholesterol in check. High pressure not only negatively affects the health of the body as a whole – it promotes the development of hypertensive retinopathy. If this pathology is not treated, it may eventually lead to a complete loss of vision. It is also worth remembering that if the pressure is higher than normal, the risks of the appearance of glaucoma and macular degeneration are also increased. And if hypertension is combined with atherosclerosis, then the vessels through which the retina receives the necessary amount of oxygen and other nutrients are damaged. This can lead to a stroke of the central artery of the retina, which, in turn, completely deprives the eyes of the affected eye.

Regularly check your eyesight. It is not difficult to follow him. It is enough to pass a small examination from an ophthalmologist in time to identify the signs of an approaching illness. Remember most eye diseases detected in the early stages can be cured and saved 100% vision. In addition, such checks will help you, if necessary, to choose the right tools for correcting it, capable of hindering the development of an already existing disease.

Eye health is in your hands. Try to keep it for a long time!

With dry eye syndrome, there is a lack of moisture on the surface of the cornea and conjunctiva due to impaired tear production and instability of the tear film. The main signs of dry eye syndrome are sensation in the eyes of a foreign body, burning and carvings, photophobia, rapid fatigue and lacrimation. Man is uncomfortable to be in rooms with dry and dusty air. If you do not take measures to eliminate the dry eye syndrome, then the development of severe consequences and serious deterioration of vision. Therefore it is useful to know about the main methods of preventing this pathology.

First, in the work behind the monitor you need to do regular small breaks. Experts recommend to break away from the screen every hour for 3-5 minutes. At this time, you can do gymnastics for the eyes, or just sit with your eyes closed. It is useful to close your eyes tightly for 5-10 seconds and then open your eyes sharply – this exercise can be repeated up to 10 times. Effective is the exercise to translate the view from afar. To do this, you need to select a point directly near the eyes, fix the view on it, and then move the eyes into the distance (for example, to distant buildings outside the window). Repeat this exercise also need up to 10 times.

Dry eye syndrome develops also because when working at a computer, a person blinks much less often than it should. Humidification of the eye surface is impaired. Therefore, you need not forget to regularly “blink”. Such an exercise contributes to the improvement of the ocular circulation.

The increased dryness of the cornea makes the eyes particularly vulnerable to infections. Do not touch the surface of the eye with unwashed hands or a stale handkerchief, it is better to use disposable napkins.

Do not abuse vasoconstrictive drops that reduce the redness of the eyes. Their regular application can lead to serious consequences and visual impairment. However, it is useful to keep at hand drops – preparations of artificial tears. They help to stabilize the balance of tear fluid on the surface of the eyes.

If you spend a long time at the computer and wear contact lens, you should pay special attention to their cleanliness and planned replacement. Some experts recommend using only one-day contact lenses. In any case, with the suspicion of developing dry eye syndrome, the time of wearing the lenses should be reduced, and with the slightest inflammation – abandon the contact correction methods for at least five days.

To prevent visual impairment, it is useful to take special multivitamin and mineral complexes for the eyes. And, of course, do not neglect the planned visit to the ophthalmologist – at least once a year. And with unpleasant sensations in the eyes, you should immediately contact a specialist. Take care of your eyes!

The correspondent of BBC Future researched the widespread belief that eye strain harms the eyesight. Strangely enough, the evidence in favor of this thesis is very vague.

If the parents at least once caught you reading in low light or in the light of a flashlight under the blanket, they certainly warned you that such eye strain harms the eyesight.
Maybe you’ve heard that it’s easy to recognize students at school because they are constantly sitting at the books and spoiling their eyesight.
Be that as it may, we all know the opinion that it is impossible to read regularly under poor lighting. However, a small study, carried out with the help of the Internet, is enough to make sure: this concern is far-fetched.

The question is closed? Not really. If you dig deeper and study scientific data, it turns out that this topic is much more complicated.
Let’s start with the simplest. Near-sightedness, or myopia, means that the person suffering from it can see things close to it, but remote objects, such as the bus number or the restaurant menu written on the board, seem to him vague.

Glasses or contact lenses help to solve this problem, but do not give an answer to the question of why some develop shortsightedness in their childhood, and some do not.
Our eyes are arranged in an amazing way: they are able to adapt to different levels of illumination. If you try to read in the semi-darkness, the pupils dilate to get more light through the lens to the retina.
With the help of this light, retinal cells – rods and cones – transmit information to the brain about what the person sees.

If you are in a dark room – for example, you have just woken up – this process allows you to gradually get used to the darkness, which at first appears pitch-black.
If you turn on the light, it will seem unbearably bright, until the pupils again adjust to the light.
The same thing happens if you strain your eyes while reading in low light. Eyes adapt to external conditions, but in some people such tension causes a headache.
Similarly, if you look at a book or sewing, bringing it close to the eyes, the eyes adjust, stretching the muscles so that the so-called vitreous body – the gelatinous mass of the eyeball, located between the lens and the retina.

Blurred lines

Unfortunately, there were no experiments devoted to the long-term consequences of reading in the dark, so we will have to rely on a variety of factors and compare the information obtained.
Most research and scientific debate on the topic of short-sightedness is devoted to the impact on the eyesight of a constant work with closely located objects, rather than reading under poor light.
For example, in 2011 in the UK a study was conducted showing that working with closely located objects can affect the development of myopia in adults, but this factor is far from as important as, for example, birth weight or smoking during pregnancy.
In some regions, short-sightedness is more widespread: in some parts of East and South-East Asia, 80-90% of school leavers suffer from myopia.

This makes scientists think about whether the fact that children have to devote a lot of time to study is not the reason for this phenomenon.
However, geographical differences in the prevalence of myopia may be associated with a genetic predisposition: there is ample evidence that the genes inherited from parents play a very important role in the development of short-sightedness.
If both parents suffer from nearsightedness, their child inherits this disease with a probability of 40%; if both have good eyesight, the risk of developing myopia is reduced to 10%.
A classic way of assessing the degree of influence of genes on the development of the disease is to compare identical twins with raznoyaytsevymi.
A study conducted among twins in the UK showed that differences in visual acuity are determined by the impact of genetic factors by 86%.
However, as the authors of the study note, this does not mean that the influence of external factors can be completely neglected. These factors sometimes play an important role.

It can be said that parents who have done a lot of themselves and, as a result, spoiled their eyesight, are likely to induce their children, and the result will be written off for a genetic predisposition.
Or, children can inherit a heightened tendency to ocular diseases, which then manifests itself under the influence of excessive eye strain at an early age.
American scientist Donald Matthey and his colleagues tried to unravel this tangle with the help of a study that was conducted in the states of California, Texas and Alabama.
They found no evidence of a genetic predisposition to eye diseases and found that children of parents with poor eyesight spend no more time on books than their peers.
The main factor, according to the authors of the study, is nevertheless heredity.

Ray of Light in the Dark Realm

Returning to the possible influence of the external environment, we can consider a number of interesting studies on the impact of lighting – not a flashlight under the blanket, but a bright daylight.
Perhaps the problem is not that we spend a lot of time in the dark, looking at the pages, but in the fact that we are little in the world.
In the Australian city of Sydney, a study was conducted involving 1,700 children aged 6 and 12 years, according to which it was found that the more time a child spends on the street, the less the risk of developing myopia.

As a result of a systematic review of the studies, including those conducted in Australia and the US, the overall positive impact of exposure to light, particularly for the population of the East Asian countries, was identified.

What can daylight help? It used to be that sports games teach children to focus their sight on distant subjects, but within the framework of this study, children could do anything while on the street in the light of day.
Apparently, to some children this helped to compensate for the harm caused to the eyes by hours of reading or studying.
The authors of the study believe that the benefit of being on the street is not so much due to the need to look afar as to the effect of daylight on the depth of field and on the ability to clearly focus the vision.
Scientists even suggested that a longer stay in the light contributes to the production of dopamine, which can then affect the growth of the eyeball.
If this hypothesis is proven, it can serve as an explanation for the low prevalence of myopia in Australia.

To what conclusion can we come with such a variety of research on this topic and with such diverse results?

Undoubtedly, genes have a great influence on the development of myopia, but one can not discount the argument that external factors also play a role.
In the end, no matter how small the impact of the situation, it is much easier to change it than its genes.
At this stage, it can only be said that outdoor games seem to be good for the eyes and, probably, young children should be engaged in good lighting, so as not to overexert vision.
Since all the studies were carried out among children whose vision was in the making, the adults do not concern these findings, so if you really want to read with a flashlight under the blanket, this is unlikely to cause you any harm.
However, since you have already grown up and you can decide when to go to bed, maybe you do not need a flashlight now either?
