Currently, there are no proven methods of preventing cataracts. However, many physicians feel it is important to include a UV screen to your prescription eyewear.

Generally, dilation of the pupil will last for three to six hours and will primarily affect your near or close up vision.

Most patients can drive home after their eye exam, and sunglasses are encouraged to be worn. Disposable sunglasses are provided for those patients who do not have sunglasses.
