A cataract is the clouding of the eye lens that puts an adverse effect on your vision. It is related to aging and is a common eye condition in older people. The condition can happen in one or both the eyes. Often eye cataracts start in one eye and then spreads to the other.

Cataract Clouding

Cataract Types:

There are two types of cataracts:

Secondary cataract – When cataract forms after an eye surgery for some other eye condition such as glaucoma. This kind of cataract can also develop in people who have some other ailments such as diabetes. Sometimes, eye cataracts are also linked to steroid use.

Traumatic cataract – This kind of cataract develops after an eye injury.

Congenital cataract – Some children are born with cataract or develop them in their childhood. It is very small but if they are big enough to affect vision, surgery is the answer.

Radiation cataract – Exposure to certain kinds of radiation can also cause cataract.

Cataract Cause:

The lens in the eye works like the lens in the camera. It focuses light on the retina that is located at the back of the eye and where the images are recorded. The lens helps to adjust the focus of the eyes, and this enables us to see things properly. The eye lens is composed of protein and water. The protein keeps the eye lens clear and allows light to go through it. However, as we get older, the protein may come together and cloud a portion of the lens. This condition is termed as the cataract. With time, the cataract may grow bigger and cloud the lens making it difficult to see. Some studies reveal that there can be more than one cataracts cause including smoking and diabetes.

Another way eye cataracts happen is when the lens grows dull over time. A brown or yellow color forms over the clear lens and it can make it difficult to read and do some other activities.
