What is cataract? 

Cataract is a common eye condition where the normally clear lens of the eye becomes cloudy. This clouding prevents light from passing clearly through the lens, leading to blurred or dim vision—similar to looking through a fogged-up window.

Causes

Cataracts most often develop as part of the natural ageing process, but they can also result from:

• Eye injuries

• Certain medical conditions (e.g. diabetes)

• Long-term use of steroid medications

• Excessive exposure to ultraviolet (UV) light

Symptoms

Typical signs include:

• Blurred or cloudy vision

• Sensitivity to light and glare

• Difficulty seeing at night

• Faded or yellowed colours
