    Your eye doctor will put a small amount of dilating eye drops into each of your eyes. It usually takes about 20 to 30 minutes for your pupils to fully open. Light-colored eyes (such as blue, green or hazel) will dilate faster than brown eyes.

    While your eyes are dilated, your vision will be blurry. You will have trouble focusing on close objects. You also will be extra sensitive to bright light. If your eyes will be dilated for an exam or procedure, bring sunglasses with you. They will help with the glare and light sensitivity when you leave your appointment.

    The effects of dilating eye drops last a few hours. Your eye doctor cannot tell you how blurry your vision will be and for how long. That depends on the type of dilating eye drop used and how your eyes react. It may not be safe to drive yourself after having your eyes dilated. You should make arrangements to have someone drive you after your appointment.

    If you have any questions before or after a dilated eye exam or procedure, be sure to speak with your eye doctor.
