Is it worth giving up glasses in case of vision loss and how to avoid this at all? There are rules of prevention, they are simple and effective.
When watching TV, working at a computer, reading a book, try not to overload your eyes. To do this, choose the right distance: to the TV screen – 3 meters, to a book, documents – 30 cm, to a computer monitor – 50 cm. The distance may be slightly different, but the image should be sharp. If sharpness cannot be achieved, consider corrective means: glasses, contact lenses. Otherwise, the eyes are overloaded and vision deteriorates. For the same reasons, make sure the room is well lit and do not read while shaking, such as on public transport.
When you lie down with a book, you cannot get the optimal position for the correct installation of the eyes, which is why vision is impaired. In addition, blood vessels in the neck are pinched, interfering with cerebral circulation.
The computer screen should be below the eyes and should not reflect. It is better that the workplace is at the window, but not against it, but perpendicularly, with lighting on the right or left. If this is not possible, be sure to provide adequate lighting. Do not forget about the right and comfortable chair so that your back and neck are comfortable and there is no tension in the muscles.
When working at a computer or with a smartphone, use computer glasses that, thanks to a special anti-reflective coating, reduce eye muscle fatigue. If you do not use glasses, order yourself one without diopters. At the same time, you will get a respectable and fashionable look.
Give your eyes a rest every hour. Do special exercises that train the eye muscles and relieve excessive tension. Periodically use "trainer glasses", they are also "with holes" – impenetrable glasses with perforations to relax the muscles.
Use moisturizing drops when working at a computer, as well as under adverse environmental conditions, when symptoms of dryness and irritation of the cornea occur. They will relieve inflammation and prevent visual impairment.
Ultraviolet rays are harmful not only to the skin, but also to the organs of vision. So wear UV-blocking sunglasses. When buying sunglasses in a store, ask if they have such protection – not all protect from ultraviolet radiation. If you wear glasses with diopters outdoors, order the version with UV protection. They can be coated with a chameleon, which darken when exposed to ultraviolet light.
If you wear contact lenses, then choose lenses with UV protection. True, dark sunglasses still do not interfere if it is very sunny outside.
Eyes need vitamins and minerals to maintain health, so be sure to include in your diet foods rich in vitamins C and E and beta-carotene, these are: blueberries and currants, fish, dried apricots, carrots, cabbage, dairy products.
There is a misconception that glasses reduce vision and therefore, when it falls, it is better to “train” your eyes by refusing them. This is a rather dangerous performance. If you have myopia, then in this way you constantly overstrain the eye muscles, the patience of which is not unlimited: at one fine moment or gradually this will lead to their breaks, which in turn will lead to retinal detachment and blindness. It is also pointless to hope for self-healing of the eyes in case of other diseases – farsightedness, astigmatism, etc. The latter also causes serious headaches.
Just the opposite is true: corrective measures, such as glasses or contact lenses, are more likely to stop the progression of the disease. As soon as you realize that you can't see well, contact an ophthalmologist. By the way, more serious diseases can be hidden behind the deterioration of vision, which are better to identify and cure in a timely manner.
First of all, in order to purchase in an online store, you must know exactly your vision parameters. They are contained in a prescription that an ophthalmologist (contactologist) writes out, or they are measured by an optometrist. If you don’t know them for sure or haven’t had your eyes checked for a long time, you feel uncomfortable – contact one of the opticians. This is convenient and can be beneficial: sometimes in optics stores, a prescription is issued when buying free of charge.
Remember that you cannot choose these medical products for yourself without consulting a doctor and checking your eyesight. You should visit an ophthalmologist if you are wearing glasses or lenses for the first time, and then see a specialist if wearing becomes uncomfortable.
