CataractsEver ask what are cataracts? A cataract is a cloudiness of the normally clear lens that sits in the front part of the eye. The lens in located inside of the eye, behind the iris, the colored part of the eye, but in front of the vitreous cavity. The lens focuses light rays on the retina in the back of the eye to produce a crisp image of what we see.

As the cataract increases in density and cloudiness, vision is often impaired. Clouded vision, the primary symptom, may make it more difficult to read, drive a car or perform daily activities.  Cataracts develop slowly over time and are a natural result of aging.  Cataract symptoms include blurry or dim vision, poor night vision, halos around lights, sensitivity to light and glare, need for brighter light for reading and other activities and a frequent need to change eyeglass prescriptions. These symptoms can progressively get worse as a cataract matures.

While the development of cataracts is a normal, age related changed to the lens due to the break-down of proteins, the rate at which cataracts develop can be hastened by trauma, diabetes, certain medications, and genetics.
