Cataracts are cloudy areas that develop within the eye lens. Since the lens in a healthy eye is clear like a camera lens, light has no problem passing through the lens to the back of the eye to the retina where images are processed.
When a cataract is present, the light cannot get through the lens as easily and, as a result, vision can be impaired. Cataracts often form slowly, causing no pain, redness, or tearing in the eye. Some stay small and do not alter eyesight. If they become large or thick, cataracts can usually be removed by surgery.
Types of cataracts include:
- Age-related cataracts. As the name suggests, this type of cataract develops as a result of aging.
- Congenital cataracts. Babies are sometimes born with cataracts as a result of an infection, injury, or poor development before they were born, or they may develop during childhood.
- Secondary cataracts. These develop as a result of other medical conditions, like diabetes, or exposure to toxic substances, certain drugs (such as corticosteroids or diuretics), ultraviolet light, or radiation.
- Traumatic cataracts. These form after injury to the eye.
Other factors that can increase a person’s risk of developing cataracts include cigarette smoke, air pollution, and heavy alcohol consumption.
