What you must know about Cataract

Unfortunately, cataract has become the leading cause of blindness across the globe; statistics claim that more than 51% of all cases of blindness across the globe are caused by cataract. As of today, about fifty-five million individuals, suffer from moderate to severe issues related to their vision because of cataracts.

What is cataract?

In layman’s terms, a cataract is a clouding effect that appears on the eye lens which will eventually lead even to a vision loss. Because of cataract, the eye lens will no longer be able to acquire necessary light to visualize objects.

There is a common misconception in the society that cataract can spread from one eye to the other. This is a wrongful assumption; simply, cataracts doesn’t spread from one eye to the other. Nevertheless, cataracts can affect both the eyes either simultaneously or one after the other due to the reasons mentioned below.

Although there are several other reasons to cause cataract, statistics emphasize that most of the cataract cases are caused because of the age. Nearly 50% of people who have reached 65 years have cataracts. Also, those who have reached 75 years have at least some sort of cataract. As we age, the proteins that form the eye lens clump together and form small cloudy areas on the surface of the lens.
