What is Legal Blindness?

Maintaining good eye care practices help our eyes last longer. But sometimes, vision loss is inevitable or genetic, and although we can still see, objects are no longer sharp, details become difficult and in some cases we become legally blind.

The definition of being legally blind refers to having a visual acuity of 20/200. This means that when comparing your vision to someone with normal vision (20/20) the person with normal vision can see an object clearly from 200 feet away, that the other person with 20/200 vision would need to be much closer at 20 feet away in order to see it with the same clarity.

Legally blind can also be defined by having a visual field limited to 20 degrees, also known as “tunnel vision,” whereas the “normal” field of vision is 180 degrees.

Some people think they are legally blind because when they take off their glasses, they aren’t able to see more than a foot away, but legal blindness refers to not being able to see better than 20/200 after your vision is corrected by eyeglasses or contacts.
