By age 75, approximately half of all Americans have cataracts. Most patients choose cataract surgery when their vision has become affected to the point where it interferes with their daily activities. One of the most common complaints is night time driving. Patients often state that driving at night has become difficult due to the glare and distorted light from oncoming headlights and other light sources. This difficulty at night can lead to safety hazards on the road and is a clear sign that an eye exam is needed.
