What is a Cataract?
A Cataract is a clouding of our natural lens of the eye. Most cataracts are related to aging and are far more common in older people. Just like with a camera, our eyes contain a lens to help you to focus on things whether they are nearby or far away. To work well, the lens must be clear. As we age, the lens of our eye gradually becomes cloudy and forms a cataract.
Looking through a cloudy lens is like looking through a dirty window — everything is blurred. Often, patients with cataracts notice difficulty with reading and driving. Night vision may also be diminished with halos or glare around lights. There may also be a general reduction in color and contrast.
By the time you reach your 60s, you may have already developed at least mild cataracts. Early on, the cataract not only makes vision cloudy, but it also makes the lens a little thicker and typically, more near-sighted. In the early stages of cataract development, changing eyeglass prescription may improve vision for a time. Ultimately however, cataract surgery may be the best option to restore sight, function, and quality of vision.
