can cataracts cause blindness
Some cataracts grow larger or denser over time, causing severe vision changes. Severe cataracts can cause loss of independence for older adults as decreased vision may affect driving, working, reading, or hobbies. While cataracts can cause blindness, this is rare. Surgery is usually done before a cataract progresses far enough to cause blindness. A rare type of cataract can lead to glaucoma.
