Vision changes that come with cataracts, macular degeneration, and glaucoma can be frightening and depressing. Talk with others experiencing the same loss about treatments and how they cope.
Cataracts
The most common symptom is a painless blurring of vision. Everything becomes dimmer, as if seen through glasses that need cleaning. Most often both eyes are affected, although vision is usually more compromised in one eye than the other.
