The condition in which eye’s natural lens (which lies behind iris and the pupil) gets clouded is known as Cataract.

Cataract is common in old-age people and is mostly observed in people of age 40 years or more. According to a report by Prevent Blindness America (PBA), there are more cases of cataracts worldwide than that of other chronic eye diseases such as macular degeneration, glaucoma, and diabetic retinopathy. It is also becoming a common cause of vision loss.

Note: As of today, more than 22 million Americans of age 40 or older are suffering from cataract. With the growing population of U.S, it is expected to have more than 30 million Americans to have cataracts by 2020.

What Are The Causes To Cataract?

For having a better understanding of the reasons that cause cataract, you must first know the basics of an eye and its lens.

The lens inside our eye works similar to that of a camera lens, which is, focusing light onto the retina for rendering a clear vision. To let us see things clearly both up close and far away, it adjusts the focus of the eye.

Our eye lens is mostly made of water and protein. The protein in the eye is precisely arranged to keep the lens translucent and lets the light pass through it. However, with the aging process, some of the protein may clump together and begin to form a cloud on a small area of the lens. It initiates the condition of cataract, and this may grow larger making it difficult to view the surroundings.

There is no probable answer for the clumping of proteins resulting in the cataract. But several studies and researches have identified some plausible factors that may cause cataracts or are in some manner associated with its development.

So, besides advancing age, here are some cataract risk factors:

  • Ultraviolet radiation from sunlight and other sources

  • Diabetes

  • Smoking

  • Hypertension

  • Obesity

  • Notable alcohol consumption

  • High myopia

  • Prior eye injury or inflammation

  • Former eye surgery

  • Hormone replacement therapy

  • Family history

  • Extended use of corticosteroid medications

  • Statin medicines used to reduce cholesterol
