(cataract) A cataract is the clouding of the crystalline lens in your eye. This opacity obstructs the passage of light resulting in a reduction of clear vision. Normally, light passes through the clear lens and is focused onto the Retina. However, the natural aging process can cause the lens to become cloudy, or milky. The cataract blocks the passage of light through the eye and causes distorted or blurred vision, glare, or difficulty seeing in poor lighting conditions. There are three types of cataracts: » A nuclear cataract forms in the lens. Those over 65 are more prone to develop this type of cataract. More than half of all Americans over the age of 65 will develop a cataract. » A cortical cataract forms in the lens, then grows from the outside to the center of the lens. Diabetics are more prone to develop this type of cataract. » A subcapsular cataract forms in the back of the lens. Those with diabetes, high hyperopia (Far-sightedness) or retinitis pigmentosa may be at a higher risk to develop this type of cataract.
