A cataract is the name of a medical condition where a cloudy, dense area forms in the eye’s lens. The condition occurs when proteins inside the eye do not allow the lens to send clear pictures to the retina. The retina is known to convert light into signals using the lens. The signals are sent to the optic nerve, which later carries the message to the brain.
The condition develops quite slowly and starts interfering with the vision. Some people develop this condition on both the eyes, but they may not happen at the same time. A cataract is common among older people.
