Cataracts occur when the lens inside your eye becomes increasingly opaque and cloudy resulting in 'foggy' vision. Cataracts are usually an age-related condition, but can occur in younger age groups.
If you have a cataract your vision will become blurry, colours may appear duller, you may also become more sensitive to glare. In the early stages of cataract, glasses may improve your vision but, as the cataract worsens, glasses will no longer offer any improvement.
In most cases cataracts can be helped by cataract surgery. Cataract surgery involves removing the cloudy lens inside the eye and replacing it with an artificial implanted lens. The implanted lens will have a prescription that is set to match normally your distance vision prescription, however there are multi-focal and reading implant options available too.
To have cataract surgery you would need to be referred to an eye specialist.
