Some vision changes are normal as we grow older. This section of our website discusses these vision changes, explains the parts of the eye and how the eye works, alerts you to symptoms of possible vision problems, and provides you with a list of questions to ask your eye doctor, including:

What is the cause of my vision loss?
Do I qualify as legally blind? If so, what does legally blind actually mean?
How can I find out about reading?

You can also learn about the different kinds of eye care professionals and the components of regular eye exams and low-vision eye exams.

How can you find out where to get a low vision exam and services?

We also offer a directory that includes private/individual low vision and vision rehabilitation service providers and clinics across the United States and Canada.
