Cataracts

A cataract is a clouding of the lens of the eye. The normally clear lens lets light enter the eye. As it becomes cloudy, less light enters and vision becomes blurry. It can be compared to a window that is frosted or yellowed. Cataracts are common with age and can occur in one or both eyes. The clouding of the lens usually happens slowly over time, but it can also happen quickly.

How quickly the cataract develops varies among individuals, and may even be different between the two eyes. Most age-related cataracts progress gradually over a period of years. Other cataracts, especially in younger people and people with diabetes, may progress rapidly over a short time. It is not possible to predict exactly how fast cataracts will develop in any given person.

Causes of Cataracts

The most common type of cataract is related to aging of the eye. Causes of cataracts include;

family history
medical problems such as diabetes
injury to the eye
medications, especially steroids
long-term unprotected exposure to sunlight
previous eye surgery
unknown factors

Treatments of Cataracts

Cataract Surgery is the only option for removing a cataract. However, if symptoms of cataracts are not bothering you much, surgery may not be needed. Sometimes a simple change in your eyeglass prescription may be helpful. There are no medications, dietary supplements or exercises that have been shown to prevent or cure cataracts.

Protection from excessive sunlight may help slow the progression of cataracts. Sunglasses that screen out ultraviolet (UV) light rays or regular eyeglasses with a clear, anti-UV coating offer this protection.

Misconceptions and Symptoms of Cataracts

There are many misconceptions about cataracts. A Cataract is not;

a film over the eye
caused by overusing the eyes
spread from one eye to the other
a cause of irreversible blindness

Common symptoms of cataracts include;

a painless blurring of vision
glare, or light sensitivity
poor night vision
double vision in one eye
needing brighter light to read
fading or yellowing of color

Cataracts are a common cause of decreased vision, particularly for the elderly, but they are treatable. The doctors at Eye Surgical Associates can tell you whether a cataract or some other problem is the cause of your vision loss and can also help you decide if cataract surgery is appropriate for you.
