"Kindness is a language which the deaf can hear and the and

Mark Twain
Blindness
"Inability to see with one or both
eyes. Transient blindness (blackout) can result from vertical acceleration
causing high gravitational forces, glomerulonephritis (a kidney disease), or a
clot in a blood vessel of the eye. Continuing blindness may arise from injuries
or diseases of the eye (e.g.,
cataract,
glaucoma), including the
retina, the optic nerve, or the
brain's visual centres. Many infectious, noninfectious, and parasitic systemic
diseases can cause blindness. Sexually transmitted diseases and
rubella in pregnant women can
cause blindness in their infants. See also
macular degeneration;
visual-field defect."

Websites "In order to determine
which people may need special assistance because
of their visual disabilities, various
governmental jurisdictions have formulated more
complex definitions referred to as
legal blindness.[2]
In
North America and most of
Europe, legal blindness is defined as
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 vision
correction—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 field of less than 20
degrees (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 is sometimes used to describe
visual acuities from 20/70 to 20/200"
