What are dry eyes?
Dry eyes occur when the eyes do not produce enough tears or their chemical composition is not right.
Causes & Symptoms
Dry eyes may be caused by the normal ageing process, hormonal changes, exposure to certain environmental conditions and issues with the normal blinking of the eyes or medications such as antihistamines, oral contraceptives or antidepressants. The most common symptoms are eye discomfort, stinging, itching or burning of the eye and/or the presence of foreign objects.
