A cataract is clouding within the natural lens of the eye which means you can’t focus clearly.
Cataracts can cause reduced vision and eventually blindness if left untreated and usually develop in both eyes at the same time. Many people who reach old age will develop a cataract.
Some groups of people are more likely to suffer from cataracts than others
Conditions such as diabetes and certain medications can result in a cataract forming, and smoking may speed up the progression of certain types of cataract.
Cataracts are painless and their symptoms can vary from person to person. They may include:
These symptoms don’t necessarily indicate a cataract, but you should always visit your optician or doctor if you’re worried.
Cataracts can be treated by a routine operation. The cloudy lens is removed and replaced by a synthetic one. The operation is usually carried out as an outpatient procedure.
If you’re worried you may have a cataract, you should visit your optician or doctor at the earliest opportunity.
