I just did some internet research to check on the exact definition of legal
blindness and came up with the following wording. Remember that the "field"
is measured in degrees, not percentage. Hope this helps.
legal blindness is defined as visual acuity
<http://en.wikipedia.org/wiki/Visual_acuity> (vision) of 20/200 (6/60) or
less in the better eye with best correction possible. This means that a
legally blind individual would have to stand 20 feet (6.1 m) from an object
to see it-with corrective lenses
<http://en.wikipedia.org/wiki/Corrective_lens> -with the same degree of
clarity as a normally sighted person could from 200 feet (61 m). In many
areas, people with average acuity who nonetheless have a visual
<http://en.wikipedia.org/wiki/Visual_field> field of less than 20 degrees
<http://en.wikipedia.org/wiki/Degree_(angle)> (the norm being 180 degrees)
are also classified as being legally blind. Approximately ten percent of
those deemed legally blind, by any measure, have no vision. The rest have
some vision, from light perception alone to relatively good acuity. Low
vision <http://en.wikipedia.org/wiki/Low_vision> is sometimes used to
describe visual acuities from 20/70 to 20/200.

Good morning everyone,
I'm scheduled to be on a local TV show this next week. The local Fox Morning
This is to promote our 8th annual Vision Awareness Walk A Thon and the White
Cane Law. On Saturday October 15.
We will tape the show on Thursday October 13 and the show will air on Friday
I know the definition of Legal Blindness is Vision less than 20/200 with a
field of vision no greater than 20%. Is this correct?
If so, does the Less than 20/200 mean corrected, I mean with glasses
As in, if you wear glasses and it brings your vision to greater than 20/200,
are you still legally blind?
