Testing for
More than 20/20
Our eye exam tests much more than 20/20
eyesight. The Snellen fractions (20/20, 20/100, etc.) are
measures of sharpness or clarity of sight (visual acuity).
20/20 just means that at a distance of twenty feet a person
can clearly see a certain size letter on the eye chart.
There's more to healthy vision than 20/20!
Our comprehensive vision exam goes beyond 20/20 to evaluate
many important visual skills, such as:
-
Visual
Acuity at Near
Is vision clear and single at close distances? Clear sight
at short distances is critical to reading, writing, close
work, computer use, etc.
-
Eye
Teaming Skills
Do the two eyes aim, move, and work as a coordinated team?
Weaknesses in binocular (two-eyed) vision and eye teaming
skills can cause numerous difficulties, including
convergence insufficiency
and poor
depth perception.
-
Eye
Focusing Skills
Do the eyes maintain clear vision at varying distances?
Rapid, automatic eye focus adjustment is critical to
learning, reading, writing, sports, etc. Deficiencies can
cause visual fatigue, reduced reading comprehension, and/or
avoidance of close work or other activities.
-
Eye
Movement Skills
Do eye movements show adequate muscle control,
tracking,
fixation, etc.? In the classroom, normal eye movements allow
rapid and accurate shifting of the eyes along a line of
print or from book to desk to board, etc. In sports,
efficient eye movements contribute to eye-hand coordination,
visual reaction time, and accurate tracking.
-
Reversal
Frequency
Is confusion or reversal of letters or words (b, d; p, q;
saw, was; etc.) within the normal ranges for a given age?
Past the age of seven, frequent visual and written reversals
might indicate a visual perceptual dysfunction.
Above are just a few of the
many visual skills
evaluated during our comprehensive vision exam. In addition,
the health of your eyes, inside and out, is carefully
evaluated for such problems as cataracts, glaucoma,
hypertension, diabetes, etc.
Vision Exams for Children
The American Optometric Association recommends
that pre-school children receive a complete vision exam at the
ages of six months, three years and five years. It is
particularly important that a child have a complete evaluation
in the summer prior to entry into Kindergarten. While in
school, yearly evaluations are recommended.
Vision Exams for Adults
The American Optometric Association recommends a yearly eye
exam for adults -- not only to detect and to diagnose vision
changes or problems -- but, also to maintain eye health. For
example, glaucoma, a disease caused by increased pressure in
the eye, commonly goes unnoticed by adults. Regular vision
examinations are also important for the prevention of vision
problems created or aggravated by today's academic and
professional demands.
