Function
-
Atropine blocks muscarinic receptors in the eye, which causes the eye muscles to relax. This causes the pupil to dilate.
Time Frame
-
The effects of atropine eye drops vary significantly between individuals. If pupil dilation, blurred vision or any other side effects persist for two or more weeks, consult your physician.
Side Effects
-
Common side effects of atropine eye drops include irritation, conjunctivitis, inflammation of the lining of the eye, eye swelling, blurring of vision, watery eyes and increased pressure inside the eye.
Warning
-
Do not drive or operate heavy machinery unless you are able to see clearly after taking atropine eye drops. Sunglasses may be provided after your test in order to minimize heightened sensitivity to light.
Fun Fact
-
Eyes with darker colored irises typically require higher dosages of atropine for complete dilation, since they do not dilate as easily as lighter colored eyes.
