Having a comprehensive eye exam is important not only to determine if you require spectacles or reading glasses (presbyopia), but also to screen for Glaucoma and detect other ocular diseases which can strike at any age. Many of these eye diseases are preventable if diagnosed and treated early. If you are over 35, we recommend that you have a comprehensive eye examination every two years. For patients over 65, a yearly eye exam is recommended. During an eye examination, it may be necessary to dilate the pupils of your eyes. After dilation, some people may have difficulty driving a car after your appointment. For this reason you may want to make appropriate transportation arrangements.
