There is no known way to prevent dry eye problems. No medication has been approved that can increase the body's minute to minute tear production. Medications that can contribute to dry eye symptoms, such as antihistamines , anticold preparations , and antianxiety medication are frequently overused. Controlling their use can be helpful. Antiparkinsonian medication contributes to dry eye, but it is unlikely that dosage can be minimized for dry eye problems without jeopardizing effectiveness for the parkinson syndrome.
Nutritional deficiency can alter tear composition and be improved following supplementation.
Dryness, wind, and heat, especially in combination can make cause a major increase in dry eye symptoms. Likewise, being in an environment with high humidity and without wind can be very helpful. Wearing of wrap around glasses or goggles with side protection can help. Water is not a good lubricant for the eye, as tears have a natural salt concentration that must be duplicated, and tears have a component of mucous as well as an oil layer. This common condition can be quite an irritating nuisance, but with good hygiene and a regular routine for eyelid care, supplemented occasionally by medication, is usually controllable.
