Over time the cloudy patches can become bigger and cover the entire lens, causing vision to become blurry.

If left untreated, cataracts can develop to a point where the affected person is effectively blind.

In most people who develop cataracts the condition can affect both eyes, although not necessarily at the same time.

Cataracts are common in older adults and limited vision can affect a person’s overall quality of life. Daily tasks, including driving, can become difficult to undertake and may even raise questions over personal safety. Pain and redness of the eye are not usually associated symptoms, however, severe conditions can cause a degree of tenderness and discomfort – especially if another eye condition is present.
