What Are Cataracts?

Cataracts occur when the normally clear natural lens of the eye becomes cloudy.

The lens helps focus the light on the retina located at the back of the eye. The retina transmits to the brain, via the optic nerve, the received luminous information in order to reconstitute an image.

When the lens darkens, the vision becomes blurred. The light received by the retina is incomplete and can not reproduce the perceived image correctly.

Cataracts can affect one eye or both eyes. Generally, the progression of this disease is quite slow and easily treatable. If a surgery is necessary, the ophthalmologist will remove the opaque lens and replace it with an artificial lens.

You should know that Bellevue clinics have all the latest technologies available to diagnose and monitor cataracts cases.
