In the UK about 1 in 3 people over the age of 65 has a cataract. Men and women are equally affected. Often both eyes are affected, but one eye may be worse than the other.
Typically, an age-related cataract forms gradually over many years. Many people with an early cataract do not realise they have it. This is because the cloudiness caused by an early cataract is mild and the vision is hardly affected. In some people, the cataract does not become too severe. However, in many cases, vision becomes gradually worse over the years.
- Blurring and haziness- although the precise pattern often varies between different people.
- Dazzling and suffering with glare
Cataract does not cause redness, pain or watering.
