Your eye is amazing! The eye is designed to take in the images from the world around you, focus the light and provide a clear picture that is sent by electrical signals to the brain.
The eye has a lens just like a camera that helps to focus the light and make a clear picture inside the eye. At birth, your natural lens is perfectly clear, just like glass.
As you age, the lens proteins start to break down and the lens becomes cloudy. This cloudy lens is known as a cataract. Many people have the misconception that a cataract is a film or cloudiness that develops in front of the eye. This is incorrect. A cataract is simply a cloudy lens. A cataract surgery is therefore a lens replacement surgery.
In this picture see how the new clear plastic lens has replaced the cloudy cataract lens, restoring clear vision.
