Dry eye usually has a good prognosis, but in severe, incurable cases, vision loss may occur and blindness may occur in advanced stages. Dry eye can cause discomfort such as dryness, foreign body sensation, and burning sensation, as well as damage to the surface tissues of the eye. Age, long-term use of contact lenses and eye drops are some of the risk factors for the disease. Mild vision loss can occur early in the course of the disease, and can usually be restored with proper rest and short-term use of artificial tears. If the disease is not treated properly or the symptoms are severe, corneal ulcers and perforations may occur. In the late stage, corneal scarring and vascularization may occur, leading to significant vision loss and even blindness. When you find dry eye, consult a doctor in time for standardized treatment, and pay attention to adjusting your daily lifestyle.
