Facts about Your Vision and The Computer
Good vision at the computer is not the same as
good vision for driving or playing golf.
The famous vision standard "20/20" is
a distance test. If you pass you can see well at twenty feet and
Your computer is at twenty inches, and the visual
skills you need for work at that distance far exceed what is needed
for driving. Workers who spend two or more hours a day at the computer
often have difficulties or discomfort that they do not attribute
to the vision because they have been told they see 20/20.
To perform well at the computer the eyes must:
- Focus for near and hold focus for an extended time
- Move smoothly and efficiently across lines of print
- Work together so both look at the same place on the screen
- Remain aware of the whole screen to find anything you are looking
None of these skills are tested in most doctors'
eye examination. All you get is a test of the health of the eyes
and a prescription, if you need one, for seeing at twenty feet.
Behavioral optometrists examine the health of
the eyes and the distance vision just as all optometrists do but
in addition they make a special series of tests of the near vision
and the skills needed for efficient and comfortable performance
at the computer.
Anyone working at a computer needs a thorough
evaluation of their vision early in their employment, before difficulties
arise that can lead to headaches, poor performance or nearsightedness,
among other symptoms.
