Dry eye is a condition that can develop under many circumstances and affects millions of people of all ages and races worldwide. In some, it may be associated with underlying medical problems. The dry eye syndrome is caused by the alteration in one's natural tear film, a thin layer of tears protecting the surface of our eyes. Artificial tears, which may be purchased at a local drug store, are the first line of therapy for dry eyes.
Artificial tears come in several different brands.
Some solutions are thicker than others. The ones which are preservative-free are recommended. A humidified environment also helps dry eyes. Several other modalities of treatment, including occlusion of the tear drainage system with a plug, exist for people with severe dry eyes. Most importantly, people with dry eyes should be examined by an eye physician to be treated for any possible causes of their symptoms.
