A cataract is a common condition that causes a clouding of the eye's natural lens, and affects millions of people each year, including more than half of all Americans over the age of 65. Cloudiness develops as a result of a buildup of protein in the lens and causes a progressive, painless loss of vision.
A cataract occurs when the normally clear lens of the eye becomes cloudy. As the cataract develops, the cloudiness no longer allows the lens to properly focus light on the back of the eye. This unfocused light causes the vision to look blurry or hazy. Development of cataracts has been associated with exposure to ultraviolet radiation. There is nothing you can do to prevent the formation of cataracts.Patients with cataracts may begin to experience troubling symptoms such as blurred vision, poor night vision, seeing halos and frequent changes in eyeglass prescriptions, which can indicate a need for treatment. Treatment of cataracts is achieved through cataract surgery, which replaces the cloudy lens with an artificial one for clear vision. Cataract surgery is the most commonly performed surgical procedure in the US, and can be performed quickly and easily with a high success rate and minimal risk of complications.
