Dilation of your pupils is necessary for a complete and thorough ocular examination. The process of dilation usually has a temporary effect on your vision causing increased light sensitivity, blurred near vision, and distorted distant vision. Dilation drops typically last about 3-4 hours but may last up to 24 hours in some individuals. While there are drops to reverse the dilation, we do not typically use them as they are only minimally effective. Please plan to have your eyes dilated during your exam. If you do not feel comfortable driving while dilated, you should plan to bring a driver with you.
