With the existence of cataract, the eye lens clarity is decreasing and light entering the eye become blocked. As people's age grow, the eye's lens generally will be slowly muddy and foggy. So cataract is a disease that commonly occurs as we grow older. Many sufferers are eventually require surgery to replace the damaged lens with an artificial lens.

This disease is commonly found in the elderly and known as an elderly cataract. In all over the world, it is estimated there are about 210,000 new cases arising each year. And more than 50% of blindness in the world are caused by cataract.
Cataract generally affects both patients' eyes with different severity. This disease can progress over the years and unnoticed by the sufferer. Cataracts do not cause pain or irritation. Patients will typically experience a vague and misty vision. Then you will see spots or blotches when the vision is less clear. This condition can also affect your view in ways such as:

However, there are several other factors that will increase the risk for developing cataracts. Among others are: being exposed to sunlight for a long time, certain diseases, such as diabetes or inflammation in the central part of the eye (uveitis), ever suffered an injury to the eye, having a family history of cataracts, unhealthy diet and vitamin deficiencies, consumption of liquor in large quantities on a regular basis, smoke.
