More questions about dilation

Who should not have their pupils dilated?

Certain health and ocular considerations may contraindicate pupil dilation. Ocular anatomy, allergies and certain medications may present a risk in pupil dilation. Dr. Venn and Dr. Hannington will carefully evaluate all risk factors prior to pupil dilation.

How long does dilation take?

Dilating drops are fast acting compounds and dilation of the pupil occurs in 20 to 45 minutes. Patients with light-colored eyes dilate faster than those with dark eyes.

How long does dilation last?

Depending on the drops used and an individual’s sensitivity to the dilating drops, the effects may last 2 to 6 hours, or more depending on the eyes’ reaction.

What are the side effects of dilation?

Most people experience mild visual side effects while dilated. Typically individuals experience a blurring of near vision and increased sensitivity to light. Distance vision is usually less affected by dilation than near vision. Driving while dilated is generally not dangerous; however some people feel safer having a driver. Wearing sunglasses is very helpful in relieving the visual side effects of dilation.

Can I drive after having a dilated exam?

You can drive as long as you are comfortable driving. You should not drive if you feel your vision is affected so much that you cannot drive safely.

Most patients are able to drive after their eye exam. The dilating eyedrops usually cause only slight blurriness in the distance. We recommend that sunglasses be worn during daylight hours to help with light sensitivity. If you are very light sensitive you may be more comfortable having someone drive you home after the eye examination. All drops used for the purposes of the eye examination have short duration activity and generally within 2 to 6 hours the effects of these drops should be worn off.
