Sight loss refers to a partial or complete inability to see, which can occur due to various factors such as age, injury, or medical conditions. Common causes include cataracts, glaucoma, and macular degeneration. People experiencing sight loss may find it challenging to perform daily activities, such as reading, driving, or recognizing faces. There are different types of sight loss, including low vision, where individuals have some remaining sight, and blindness, which means a total lack of vision. Rehabilitation services and assistive technologies, like magnifiers and screen readers, can help those affected adapt and maintain their independence.
