Glaucoma cannot be prevented. It often has no early symptoms. The vision loss caused by glaucoma cannot be reversed.

Early treatment can help protect your vision

By the time you notice problems with your vision, you may already have lost a lot of sight. Regular eye exams that check for glaucoma and other eye diseases can help find problems early. 

Glaucoma is treated by ophthalmologists (medical doctors who specialize in eye care). In some states, optometrists (healthcare professionals who provide basic eye care) can also treat glaucoma.
