The term "eye disease" is a broad and general description that refers to any condition or disorder affecting the eye, its surrounding structures, or vision. These conditions can range from mild to severe, temporary to permanent, and may be caused by various factors such as genetics, injury, infection, aging, or exposure to certain substances. Some common examples of eye diseases include cataracts, glaucoma, macular degeneration, diabetic retinopathy, conjunctivitis, and strabismus. Treatment for these conditions may involve medications, surgery, or other interventions to help preserve vision and maintain ocular health.
