Cataracts

---

A cataract forms when the crystalline lens becomes cloudy, leading to changes in your vision. A person with cataracts may experience a decrease in their vision (especially at night), glare, changes in their refractive error and faded colours.

Cataracts can develop at any age but are more commonly seen in individuals over the age of 60. Other factors that may contribute to cataract formation include genetics, smoking, diet, diabetes, medications and sun exposure.

Cataracts can be removed with surgery - the cloudy crystalline lens is replaced with an implant, called an IOL.
