Cataracts
Cataracts occur when the normally clear lens inside the eye becomes cloudy.
Cloudiness blocks or scatters light, leading to blurred or reduced vision. Most cataracts develop due to ageing and long‑term exposure to ultraviolet (UV) light.
Other causes include eye injuries, certain medical conditions, exposure to toxic substances or radiation, and rare congenital causes, such as maternal rubella or genetic factors.

Cataracts FAQs
How do I know if I have cataracts?
A comprehensive eye examination can detect cataracts, even before symptoms appear. Optometrists use specialised equipment to assess changes in the lens.
Can cataracts be prevented?
There is no proven way to prevent cataracts, but reducing UV exposure may help. Wearing a brimmed hat and approved sunglasses outdoors is recommended.
What are the signs of cataracts?
Cataracts usually develop slowly and painlessly. Common symptoms include blurred or hazy vision, increased glare or sensitivity to bright lights, double vision in one eye, faded colours and/or difficulty seeing at night.

Other Cataracts FAQs
No. Cataracts are not a growth or film on the eye. They are caused by changes within the lens material itself.
Yes. Cataracts usually progress gradually, becoming denser over time. The rate of progression varies widely—from months to many years.
Cataracts commonly occur in both eyes, though they often develop at different speeds.
Cataracts are very common in people over 65. Regular eye examinations help detect changes early.
If left untreated, cataracts can lead to significant vision loss. Early detection and timely surgery can prevent this.
Surgery is usually recommended when cataracts begin to interfere with daily activities such as reading, driving or recognising faces. Your optometrist can guide you on timing.
Cataract surgery is now a routine, minimally invasive procedure, often performed under local anaesthetic. Many patients go home the same day. The operation is carried out by an ophthalmologist, and your optometrist will refer you if surgery is needed.
Most people see very well after surgery. An artificial intra‑ocular lens (IOL) is usually placed in the eye to replace the cloudy natural lens. Some people may still need glasses or contact lenses for certain tasks.
