overwear syndrome


overwear syndrome

 [o″ver-wār] extreme photophobia, pain, and lacrimation associated with contact lenses, particularly non–gas permeable hard lenses, usually caused by wearing them excessively. Prolonged lens-induced corneal hypoxia results in corneal epithelial edema and eventually erosion; it can be a chronic condition or an acute episode that usually occurs several hours after lenses are removed.
