Just think, a billion of the living people on our planet experience vision problems simply due to the lack of timely prevention and treatment. A timely operation or selected glasses would help many of us to retain the ability to see. The material is timed to coincide with the World Vision Day.

Does everyone go blind with time?

Really, 65% people over 50 have eye problems. But this does not mean that after the 50th birthday, everyone is moving towards blindness.

Every ten years, the vision is reduced by 1-3 angles: we begin to see less if we do not shake our head. The photoreceptors of the eye become less sensitive and we do not distinguish colors as clearly as when we were young. Small changes in the vitreous body lead to “flies” before the eyes.

These are not very pleasant, but not terrible changes. Usually they don’t even threaten them with glasses, let alone the operation. But to make sure that the changes are within the norm, only an appointment with an ophthalmologist will help.

Do conjunctivitis and barley impair vision?

No. Just like some other eye diseases, neither conjunctivitis nor barley does not lead to blindness. Among the relatively harmless diseases for vision, WHO calls such:

  • inflammation of the eyelids;
  • conjunctivitis;
  • dry eye syndrome;
  • barley;
  • benign neoplasm;
  • subconjunctival hemorrhage.

What problems most often lead to loss of vision?

Factors such as genetic predisposition, smoking, poor hygiene and medical conditions such as diabetes affect eye problems.

Some conditions are more likely than others to impair or lose vision:

How to keep your eyes?

  • Protecting your eyes and vision is easy if you think about it beforehand. American Academy of Ophthalmology proposes such methods:
  • Wear sunglasses that block UV rays. Ultraviolet light contributes to the development of cataracts.
  • Quit smoking. Smokers are more prone to macular degeneration.
  • Eat varied. Add a variety of vegetables to your diet, not just carrots.
  • Check your eyesight at 40, even if your eyes are okay. The first age-related changes appear just at this age.
  • Do not miss the planned visit to the ophthalmologist. The same cataract can be cured if it is detected early.
  • Use protective shields or goggles during sports, repairs, or other activities where accidental eye injury could occur.
  • Find out what eye diseases your relatives have. Perhaps you should have your vision checked before you wait forty.

Taking care of your overall health, such as keeping your blood pressure and blood sugar levels under control, can also help you delay prescription for glasses or avoid wearing them altogether.
