CataractsWhat is a Cataract?

A cataract is one of the more common causes of vision impairment. A cataract is the clouding of the lens in the eye due to age-related change. The lens is located behind the iris (pupil) which is the coloured part of the eye. A cataract affects a person’s vision like a dirty camera lens that interferes with the light and images formed by the light falling on the retina.

Signs and Symptoms

Vision impairment due to cataract occurs gradually as the cataract develops over time. At some point, your glasses or contact lenses may no longer offer adequate vision correction. You may experience blurred vision, difficulty reading, dull colours, increasing light sensitivity and glare from headlights while driving at night.
