A cataract is a clouding of the normally clear lens of the eye, which interferes with the normal passage of light rays to the retina. The result is a general dimming of vision which becomes progressively more blurred as the density of the cloudiness increases.

Causes can be:

  • Ageing
  • Injury
  • Disease
  • Radiation
  • Chemicals
  • Excessive Ultraviolet (UV) Light

Most age-related cataracts develop from an excessive build up of protein.

When a cataract is small, the cloudiness affects only a small part of the lens. You may not notice any changes in your vision. Cataracts tend to “grow” slowly, so vision gets worse gradually.

Some symptoms are:

  • Car headlights appearing too bright at night
  • Glare from lamps or sun
  • Halos or haze around lights
  • Decreased vision in bright light

Some people with a cataract find that their vision close up suddenly improves, but this will be temporary. Vision is likely to reduce further as the cataract develops.
