How to cure the dry eye syndrome?
Syndrome of the dry eye can be cured as follows:
- With the help of "artificial tears" - eye drops that are chemically composed to resemble tears; these drops hydrate eyes, protect from drying out, reduce friction between retina and eyelids;
- "Artificial tears" should be used constantly, 2-4 times a day as necessary. If there is a need to use "artificial tears" very frequently, preference must be given to the "artificial tears" of thicker consistency (gel-like, ointments). Also "artificial tears" without preservatives are available, in case patient has an allergic reaction to the preservatives;
- In more serious cases also occlusion of the points of tears (short-term or permanent) or surgical closing must be performed to prevent leakage of tears to the nose;
- It is recommended to moisture dry air with bowls of water, humidifiers during the heating season. Also green plants moisturize air. You should avoid premises where people smoke, blow dryers, ventilators, air conditioners;
- It is recommended to use maximally covering protecting glasses when going out in wind.
