 What is cataract? ( मोतिबिंदू )


  I have heard a lot of cases of people having cataract disease. But what exactly is it? Was a real big question for me. Let's know now...

  A cataract is an eye disease. Each of our eyes consists of a transparent lens. Our eye lens is made up of water and protein. They are arranged in such a way that keeps the lens clear, and lets light pass through it. Hence, a sharp image is formed on the retina.

  However, as we age, the protein begins to clump together, making the lens cloudy. This clouding of our eye's natural lens is called a cataract.

  In such situations, when light from an object enters our eye, the clumped protein blocks or scatters the light. As a result, a blurred image is formed on the retina, thus making it hard to see.

  This is treated via various methods.
