How It Feels
There normally is no discomfort involved with a slit lamp
examination.
Dilating drops may make your eyes sting and cause a medicine taste
in your mouth. You will have difficulty focusing your eyes for up to 6 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.
Anesthetic drops usually wear off in about 30 minutes.
