A cataract is a clouding of the normally clear lens in your eye. This causes images to appear cloudy, as if you are looking through a foggy window. Cloudy vision caused by cataracts can make it more difficult to read, drive a car (especially at night), or distinguish the details of a face from a distance. Most cataracts develop and progress slowly, without pain. They may not disturb your vision early on, but with time, cataracts will eventually interfere with your vision.

At first, brighter lighting and eyeglasses can help you overcome the blurred vision caused by cataracts. However, if glasses don’t work and the impaired vision interferes with your usual daily activities, you might be a candidate for cataract surgery. Fortunately, cataract surgery is generally a safe, effective procedure.

If you believe your vision is being affected by cataracts, you should see an ophthalmologist (Eye M.D.). Optometrists are not qualified to perform cataract surgery. EyeMDs.org has a comprehensive list of cataract surgeons in your area.
