Know about Cataract

Cataract is a very common eye problem. It is affecting more than 60% of the population over the age of 60. The cataract eventually leads to visual destruction and then blindness, therefore it is necessary to remove cataract with the surgery. First of all you need to be aware about what is cataract and various causes of cataract.

A cataract influences the lens of the eye. The lens becomes clouded. The light coming from outside passes through the lens and reaches the retina to form a picture of what you are viewing. In case of cataract, the light scatters when is passes through the lens due to the cloud and fails to form a clear picture. Thus the image formed is blurry and distorted. This is the reason why people suffering from cataract have a blurry and distorted vision. With time the cloud become denser and eventually leads to blindness.

Though Cataract basically develops during the old age but that are times when cataract is present at the birth time. Also, sometimes it develops in the early days of childhood because of the genetic history. The actual reason of developing cataract has not yet been discovered. Some say that is developing due to the change in the structure of protein of the lens that happens over the years. In most of the cases, both the eyes are affected by the person though the rate of growth of the cataract in an eye will be different from another.  Cataracts have also been a result of the intraocular inflammation, severe trauma, or previously performed eye surgery. The other reasons that can lead to the cataract formation in the early years are smoking, some medicines, diabetes or extreme exposure of the eye to the ultraviolet rays.
The growth of the cataract is a very slow process and it develops gradually with time. The person suffering from cataract will start to have problems with the vision.  It will become difficult for him/her to carry out their day to day task like reading and writing. The vision becomes blurry and distorted.  Everything appears to be cloudy and the colors seem dull. They are not as bright as they were before. The glare will start troubling you more and you will start seeing halos around the lights.
