Cataract is a clouding of the eye's lens. When we look at something, light rays travel into our eye through the pupil and are focused through the lens
onto the retina, a layer of light-sensitive cells at the back of the eye. The lens must be clear in order to focus light properly onto the retina.
If the lens has become cloudy, this is called a cataract.
Vision problems with cataracts
If your vision has become blurry, cloudy or dim, or things you see are not as bright or colorful as they used to be, a cataract may have developed
in one or both of your eyes. Many people say that their vision with cataracts is similar to the effect of looking through a dirty car windshield.
As a cataract slowly begins to develop, you may not notice any changes in your vision at first. But as the cataract progresses, you may begin to
find that it interferes with your daily activities. Performing a complete eye exam, your ophthalmologist can tell you whether cataract or another
problem is the cause of your vision loss.
While cataracts are one of the most common causes of vision loss, especially as we age, they are treatable with cataract surgery. Since most cataracts
are part of the normal aging process, they cannot be reversed. There are no medications or eye drops that will make cataracts go away—surgery
is the only treatment.
