What does
20/20 Vision Mean?
20/20 vision is a term used to express normal
visual acuity (the clarity or sharpness of vision) measured at a
distance of 20 feet. If you have
20/20 vision, you can see clearly at 20 feet what should normally be
seen at that distance. If you
have 20/100 vision, it means that you must be as close as 20 feet to see what a person with normal vision can see at
100 feet. 20/20 does not necessarily mean perfect vision. 20/20
vision only indicates the sharpness or clarity of vision at a
distance. There
are other important vision skills, including peripheral awareness or
side vision, eye coordination, depth perception, focusing ability
and color vision that contribute to your overall visual ability.
Some people can see well at a
distance, but are unable to bring nearer objects into focus. This
condition can be caused by hyperopia (farsightedness) or presbyopia
(loss of focusing ability).
Others can see items that are close, but cannot see those far away.
This condition may be caused
by myopia(nearsightedness).
A comprehensive eye examination by a doctor of optometry can
diagnose those causes, if any,
that are affecting your ability to see well. In most cases, your
optometrist can prescribe glasses,
contact lenses or a vision therapy program that will help improve
your vision. If the reduced vision is due to an eye disease, the use of ocular medication or other treatment
may be used.
