Dilating Eyes Before An Eye Exam

Has an eye doctor ever dilated your eyes? Eye dilation has been a common part of the eye inspection process for decades. If you’ve ever wondered why that is, we’re here to help.

What is Eye Dilation?

The eye dilation process involves the application of a special compound that dilates the pupils. This can involve an eye dropper or a spray. The compound blocks the parasympathetic receptors in the sphincter of your iris, which in turn prevents the muscles in the sphincter from contracting. This keeps your iris open to let more light in, allowing your doctor to better see your retina as well as other parts of your inner eye.

Eye dilation is used to inspect for the following conditions:

Side-Effects of the Dilation Process

The most common side-effect of eye dilation is light sensitivity and blurry vision for 4 to 24 hours after the exam. It’s strongly recommended that patients don’t drive until these symptoms go away, so you may want to arrange a ride with a friend or call an Uber. Some patients have mild allergic reactions involving redness, swelling near the eye, or dry mouth.
