As we age, the topic of cataract becomes more and more talked about in our circles. “Few of my friends have had cataract surgeries. What is cataract? Will I get it too?” This post answers these questions for you. Take a look at the post and get updated on the Causes of cataract.

What is cataract?

Cataract is the clouding of the lens in the eye, that causes blurry or unclear vision. The eye’s lens is very much like the camera’s lens. It captures light from the surroundings and focuses the captured light onto the retina. This is how we get our vision. The lens adjusts the focus of the eye according to the distance of the things.

Normally, cataracts are associated with aging, but there are various other reasons for the occurrence of cataracts, such as:

  • Ultraviolet radiation from sunlight and other sources
  • Diabetes
  • Hypertension
  • Obesity
  • Smoking
  • Prolonged use of corticosteroid medications
  • Statin medicines used to reduce cholesterol
  • Previous eye injury or inflammation
  • Previous eye surgery
  • Hormone replacement therapy
  • High alcohol consumption
  • High myopia
  • Family history

There are no conclusive proofs as to why cataracts occur as we age, but studies are still being conducted to find the connection between aging and cataract.
