What are cataracts?

Cataracts are when the lens in the eye becomes cloudy, causing your vision to become blurry in some cases. This is a very common condition that is the main cause for sight impairment around the world.

What are the symptoms of cataracts?

Symptoms of cataracts include:

  • Blurred, cloudy or misty vision

  • Glare from bright lights

  • Double vision

  • Colours appear faded and washed out

  • You struggle seeing in low light conditions


What causes cataracts?

In most cases cataracts develop after the age of 65; it is a normal aging process of the eye. However there are other factors which increase the risk of developing cataracts such as:

  • Prolonged UV exposure

  • Smoking

  • Diabetes

  • Eye injury

  • Long-term use of steroids

  • Excessive drinking of alcohol

  • Genetics


What treatments are available for cataracts?

Cataracts often start of as mild and develop over time. If your cataracts are mild, often a new prescription and better lighting can help with symptoms. However if the cataracts become more severe the only effective treatment for cataracts is cataracts surgery. This is a common surgery that many people have done. It involves replacing the cloudy lens with a clear artificial lens. Your optometrist will refer you to have this done if your vision is below a certain level and if it is affecting your daily life.
