What are cataracts and how do I know if I need surgery?

A cataract is a clouding of the eye's natural lens, which lies behind the iris and the pupil. The lens is made mostly of water and protein. As we age, some of the protein may clump together and start to cloud a small area of the lens. UV rays contribute to cataract development. Over time, the cataract can grow. Your vision becomes blurred, like looking through a cloudy piece of glass, and light from the sun or a lamp seems too bright. Also, you notice when you drive at night that oncoming headlights cause more glare than before.
When cataracts reduce your vision to the point that they interfere with your daily activities, then it's time to have them removed. If you think you have a cataract, come see me for an exam and find out for sure.
