A cataract is a condition where the clear lens of the eye clouds over due to the breakdown of proteins in the lens. In advanced cases of cataracts, the pupil can appear grey or white.1 The condition reduces the amount of light that reaches the retina, which can lead to visual impairment like:
- Blurred or foggy vision
- Sensitivity to light
- Distortion or double vision
- A brown or yellow shade to objects.2
In severe cases, cataracts can lead to blindness. Cataracts are usually age-related, with half of all Australians developing cataracts by age 50, and most people over 70 having some level of cataract formation.2 Therefore, if you’re approaching this age group (or are already in it) it may be worth checking if cataract surgery is included in your current policy.
Some other factors that can increase your chances of cataracts include family history, prolonged steroid use, previous eye injuries, radiation treatment on your upper body for conditions like cancer and long exposure to UV light with inadequate protection.2
