How It Feels
You should not feel any discomfort
during these vision tests.
When dilating eyedrops are used
Dilating drops may make your eyes sting and cause a
medicine taste in your mouth. You will have trouble focusing your eyes for
up to 12 hours after your eyes have been dilated. Your distance vision usually
is not affected as much as your near vision, though your eyes may be very
sensitive to light. Do not drive for several hours after your eyes have been
dilated. Wearing sunglasses may make you more comfortable until the effect of
the drops wears off.
