A cataract is a clouding of the lens in your eye, which causes blurred vision.

If you’ve been diagnosed with cataracts, or you suspect you may have a cataract, there’s no need to worry. Cataracts are very common, and occur naturally with age. They are also very easily treated.

Cataract symptoms

A cataract is a clouding of the lens of the eye, which causes blurred vision. A cataract is not a visible film on the outside of the eye, and you may not even be aware that it is developing, as they usually develop over time. Common cataract symptoms include:

  • Deterioration of your distance and reading vision
  • Hazy, fuzzy, blurred or double vision
  • Increased sensitivity to light and glare
  • Difficulty driving at night
  • No improvement in vision, even with stronger glasses

Causes of cataracts

Cataracts occur naturally as a result of the ageing of the eye, and diagnosis of cataracts in adults over 40 is quite normal. They also sometimes occur in infants and children as a congenital defect.

Normally, the lens at the front of the eye focuses light onto the retina at the back of the eye, creating a sharp image. When the lens becomes cloudy, light cannot pass through freely, and your vision becomes blurred.

Contrary to popular belief, cataracts are not caused by over-use of the eyes, nor can they be made worse by using the eyes.
