With the help of our eyes, we perceive the world around us in all its variety of colors.But over time, the contours of objects lose clarity and colors fade.This does not happen because the world has changed, but because of a decrease in visual acuity.This problem can affect anyone.To prevent this, it's important to know how to improve your vision when it starts to decline.
How urgent is the problem of loss of visual acuity?
According to statistics, more than 290 million people have low vision, about 40 million are completely blind.In big cities, 8 out of 10 residents have various visual dysfunctions, and in the world at least 1 adult becomes blind every 5 seconds.
The statistics are not at all encouraging and make us think seriously about eye health.In 75-80% of cases, the loss of visual function can be prevented if it undergoes therapy in the early stages of the development of ophthalmic diseases.
The reason for a decrease in visual acuity can be the influence of the external environment, as well as an unbalanced diet, hereditary predisposition, etc.But genetics cannot be fooled, and other factors can somehow be "neutralized".
Only a specialist knows how to improve vision and cure diseases that lead to vision loss.Therefore, every year it is necessary to carry out diagnostics to assess the health of the organs of vision and the whole body.
How to improve your vision quickly?
Everyone can minimize the damage of external factors and adjust their lifestyle.We have prepared for you the 10 most popular ways that will help you improve your vision and prevent its complete loss.
Don't forget sun protection
Ultraviolet radiation, the main source of which is the sun, is invisible to the human eye.But contrary to the common belief that only direct rays are harmful to the eyes, radiation reflected from surfaces is no less dangerous.The bright sun encourages faster evaporation of tear fluid.Because of this, the feeling of dryness and burning often increases in the summer.
Many people do not suspect that long-term exposure to the sun can lead to the development of conjunctivitis, photokeratitis (burns and inflammation of the cornea) and cataracts.But you can protect your eyes from the sun.To do this, you need to wear glasses that help reduce radiation damage at any time of the year.But only good glasses with a protection level of UV 400 or UV 380 can handle ultraviolet radiation.
There are also glasses with cosmetics labels.But they have nothing in common with UV eye protection products.These are more of an image accessory than sunglasses.
Protect your eyes from injury
When working with an open flame, chemicals or a welding machine, do not forget to protect your eyes.Without glasses, you cannot perform tasks that pose a danger to the organ of vision, because you can injure yourself or get burned.
You must also remember to take precautions when working with stone chips, shavings and any small objects that can damage your eyes.Special glasses are useful not only at work, but also at home.
Take vitamins that improve eyesight
Vitamins such as A, D, C, E are considered extremely useful for eyesight.Minerals, such as zinc, also provide benefits.These active substances help prevent macular degeneration (responsible for central vision).
Cold-pressed vegetable oil will also be beneficial for vision.It can be fennel oil, pumpkin oil or pine nut oil.To reduce your risk of developing cataracts, you need riboflavin, vitamin B2 and beta-carotene.These substances are present in tomatoes and watermelon.
To keep your eyes healthy, you should also eat other foods that improve your vision.These can be natural sources of omega-3 fatty acids (salmon and flax seeds), fresh fruits and vegetables (carrots, broccoli, red peppers, kale, sweet potatoes, citrus fruits, strawberries).It is difficult to definitively say which foods improve eyesight.But the diet of a person who wants to preserve it must contain vitamins and minerals that are important for the body.
Take a break from the computer
Many people, after a working day spent in front of the monitor, sit down again at the computer at home to finish work or just watch their favorite movie.But such loads on the visual apparatus are unacceptable.
The 20x20x20 rule will help reduce the negative effects of eye strain.It can be easily deciphered: when working with digital information, you must take a 20-second break every 20 minutes.At this moment you should look at the object that is 20 meters away from you.
It is useful to blink often during visual stress, because when performing tasks that require a high concentration of attention, the frequency of blinking is reduced.Because of this, the tear film quickly evaporates and discomfort occurs.
If the mode of work and rest at the computer is disturbed, dry eye syndrome (DES) can occur.This condition is usually treated with eye drops.But they are not able to improve vision or provide the eyes with enough moisture.Drops are only a temporary measure to eliminate the unpleasant symptoms of dry eye syndrome.Such drugs do not normalize tear production, therefore they are only suitable for symptomatic treatment of dry eye syndrome.
Don't forget eye exercises
After long, monotonous work at the computer, it is useful to give your eyes a "training".Visual gymnastics consists of simple exercises that help release the heavy tension of the eye muscles and get rid of the feeling of heaviness.Incorporate three simple exercises into your daily routine:
- Narrowing his eyes.While sitting on a chair, close your eyes tightly for a few seconds and open your eyes again.Repeat the exercise 8-10 times with a break of 5-10 seconds between sets.
- "Running eyes."Stand on your feet and slowly move your gaze from side to side, from bottom to top.
- It will blink.Try to blink your eyes very often for 1-2 minutes.Despite the simplicity of this exercise, it is very useful, as it helps to stimulate blood circulation in the eye tissues.
Is it possible to improve eyesight with gymnastics?Of course, exercises will not help restore 100% vision in 5 minutes, even if you do them every day.But periodic training of the visual apparatus will help prevent the development of serious ophthalmic diseases.
Of course, exercises will not help to completely restore vision, but they can relieve muscle tension, stimulate tear ducts, and improve nutrition and tissue blood supply.
But eye exercises are not always helpful.It should not be performed in cases of retinal detachment, inflammatory ophthalmic diseases or immediately after surgical treatment of eye pathologies.Overloading the visual apparatus in the presence of such conditions can only worsen its condition.
Control your body weight
Excess weight can be one of the reasons for deterioration of the visual system.As paradoxical as this may sound, it is true.Many obese people suffer from type 2 diabetes, which leads to the development of diabetic retinopathy.When there is a lot of sugar in the blood, the walls of the arteries in the retina are damaged.Because of this, vision deteriorates.
Another complication of diabetes that can cause poor vision is neuropathy.It can affect any part of the nervous system, including the optic nerves.Weight control and physical activity help prevent the development of type 2 diabetes and its eye complications.
Obesity is also often accompanied by hypertension, which in turn negatively affects the visual system.In order to normalize blood pressure, you not only need to take special medications, but also perform physical exercises that will help you control your weight.
Giving up bad habits will help maintain visual acuity
Smoking, drinking alcohol and other bad habits are harmful to health.They also suffer from gas.For example, smoking can increase the risk of developing cataracts and age-related macular degeneration.But not only nicotine is harmful, because cigarette smoke irritates the mucous membrane and can even contribute to its dehydration (drying).
But this can be avoided by giving up bad habits.It is a fact that eye vessels can recover after quitting cigarettes.So think about your health before you smoke another cigarette.
Don't forget about antioxidants
Every day, the visual system is exposed to oxidative stress, which anthocyanins help to neutralize.These beneficial antioxidants are present in a variety of berries, such as cherries, blueberries, blueberries, and currants.They help reduce the risk of developing dry eye syndrome (DES).
This disease is characterized by a decrease in the production of tear fluid and (or) a change in its composition.Normally, the precorneal film should nourish, moisturize and protect the cornea.But due to the lack of tears, it quickly loses stability, becomes thin or completely atrophies.
Increased evaporation of tears causes drying of the protective film.Typical dry eye symptoms appear: itching, redness, burning, tearing, foreign body sensation, etc.If left untreated, dry eye can lead to inflammatory eye diseases, damage to the cornea, and even ulcers on its surface.
Researchers in Japan have found that the most effective source of antioxidants for eye health is Aristotelia Chilean extract.It contains delphinidins, which have a direct effect on the lacrimal glands and help improve their functioning.They absorb free radicals that damage tear gland cells and neutralize the effects of oxidative stress.This helps reduce the risk of developing diabetic rhinopathy, glaucoma, macular degeneration, cataracts and other diseases that can lead to vision loss.
Analyze the legacy
If one of your relatives (grandparents, parents) had vision problems, there is a chance that this problem will be inherited.This is especially true for macular degeneration, glaucoma and optic nerve atrophy.
These diseases usually have a genetic nature.Therefore, if someone in your family had such a diagnosis, special attention should be paid to prevention.
Remember hygiene
The visual organs are very sensitive to infections and pathogenic microbes.Therefore, everything that comes into contact with the eyes should be as clean as possible: hands, handkerchiefs, towels, etc.And, of course, contact lenses.It is necessary to strictly follow the rules of care for them, regularly disinfect them and change them after the end of their working life.
Lenses should be changed in accordance with the manufacturer's recommendations and regularly disinfected.Otherwise, you run the risk of simply getting an eye infection.
