Causes & Symptoms of Cataracts

What causes cataracts?
Most cataracts form as a normal part of the natural aging process and are present in half of adults over age 65. Other causes of cataracts include trauma, certain drugs or diseases such as diabetes. To a lesser degree, some babies are born with cataracts or develop them soon after birth, but this is rare.

How a cataract develops

cataract in the eyeThe natural crystalline lens in the eye is made mostly of water and protein. A cataract is when some of this protein clumps together, causing the natural lens in the eye to become discolored and cloudy.

Eventually everyone will develop cataracts. …..unless they have already had Clear Lens Replacement in the past.

The development of cataracts is usually a very slow process. In its early stages, eyeglasses are effective in relieving visual issues, however, as time goes on and the cataract worsens, the only way of restoring vision is with cataract surgery. Cataract surgery involves removing the cloudy natural lens in the eye and replacing it with a new artificial lens, called an Intraocular Lens Implant or IOL.

What are some common symptoms of cataracts?

  1. Blurred Distance Vision: Vision in general starts to blur, but it is especially noticeable when driving or watching TV from a normal distance.
  2. Sensitivity to Glare: Many people find it difficult to drive towards the sun. They also find it harder to see golf balls against a bright sky, even though vision may seem acceptable under other circumstances.
  3. Night Blindness: Because a cataract allows less light through the lens, it may become more bothersome in low light conditions, especially when trying to drive at night.
