A cataract is a clouding of the lens in the eye that affects vision. The lens is a clear part of the eye that helps to focus light, or an image, on the retina. The retina is the light-sensitive tissue at the back of the eye.
In a normal eye, light passes through the transparent lens to the retina. Once it reaches the retina, light is changed into nerve signals that are sent to the brain. The lens must be clear for the retina to receive a sharp image. If the lens is cloudy from a cataract, the image you see will be blurred.
Typical symptoms of a cataract may include:
- Cloudy or blurry vision
- Colors seem faded
- Glare – headlights, lamps or sunlight may appear too bright
- Seeing halos around bright lights
- Double vision or multiple images
- Poor night vision
- Frequent prescription changes for glasses
Cataract surgery is a procedure to dissolve the cloudy lens of your eye, and in most cases, replace it with an artificial lens. In many cases, the new lens can restore your vision to 20/20 eyesight. The Eye Clinic offers several types and brands of lenses, including premium lenses, depending on a patient’s need.
