For whole days, streams of visual information are falling upon us, which our eyes must have time to perceive. Therefore, the best we can do to maintain our vigilance is to observe a number of simple rules. So, what you need to know for those who decide to ask themselves how to preserve vision:
1. Give the eyes after intense visual work a short break during which you can do gymnastics for the eyes. This is a good prevention of accommodation spasm, with long-term existence of which visual acuity can significantly decrease . There are many techniques to reduce it, which should not be neglected. Systematic eye training will make the question of how to preserve vision irrelevant. If there is no time to do exercises for the eyes, but still want to see well, then it is possible to try the use of phenylephrine preparations, but only after consulting a specialist.
2. Frequent blinking allows you to restore the precorneal film of the eyes, which is often disturbed by prolonged non-blinking. This is the prophylaxis of the dry eye syndrome (CVD), which is becoming increasingly important. Long-term CVH can be the cause of not only constant discomfort, but also serious changes in the cornea of the eye - xerosis and keratopathies. Unfavorable environmental factors such as air conditioners, commonly used hair dryers, tobacco smoke, the use of various aerosols, the general gas contamination play an important role in the development of CVH, and it is also worth noting the lack of vitamins, the imperfection of their own tear-producing system, and the abuse of contact lenses. And how to maintain vision in such adverse conditions? When the first symptoms of CVH appear, artificial tear preparations should be purchased , which are widely available on the pharmaceutical market.
3. Show any motor activity, attend massage sessions, especially the cervical-collar zone, which stimulate blood circulation, and, consequently, nutrition in the organ of vision.
4. More often to be in the fresh air, to minimize bad habits. Especially smoking leads to a violation of the microcirculation in the retina, which adversely affects the nutrition of photoreceptors.
5. Use vitamins and minerals useful for the eyes: A, B6, B12, B1, E, D, and Ca. How to maintain vision with these substances? Very simple, they should be included in the daily diet. They are found in many foods and vitamin complexes. A special place in modern ophthalmology is given to such unique substances as lutein and zeaxanthin. This is a very good prevention of age-related macular degeneration and cataracts.
6. Avoid colds, sore throats, sinusitis, dental caries, which are sources of eye diseases leading to decreased vision. It is the prevention and rehabilitation of chronic foci that helps in the important issue: how to maintain vision.
7. And, last, you need to sometimes see an ophthalmologist. This is especially important after 35 years, because a disease such as glaucoma is more often manifested after overcoming this age limit. Medicine is still powerless in its cardinal treatment. Therefore, it is better to detect it in time and begin treatment as soon as possible in order to maintain objective vision.
Can vision be improved today if it was initially lowered? Ophthalmologists give a very optimistic answer to this question. If the patient has a refractive decrease in vision, which has not progressed for a long time, then by the age of 20 he can very well afford a refractive laser operation that corrects and restores vision.
