The Vision Screen
9000 package consists of a CD, red/green glasses, and a penlight. The
user loads the program into any personal computer running Windows 98SE or
later, and follows the program’s instructions. An assistant is needed to
help administer some of the tests, but no special skills are required. It
takes about 15 minutes to complete all the testing procedures.
The results of a person's vision screening are displayed by the program on a
printable report form. Any number of report forms can be stored in the
program's database, a handy feature for those who wish to track their vision
over time, or for schools and other organizations that wish to test many
people and keep the results on file.
Vision Screen 9000 is NOT a substitute for regular visits to an
optometrist or ophthalmologist. It is intended to be a supplement to
professional eye care, a way for lay people to quickly and comprehensively
screen their vision for possible problems.

walking on steps and escalators, and many sports. If this test is hard, you
do not use your two eyes together correctly. Depth perception problems can

defects will not affect your sight or eye health. Changes in color vision
