A cataract is a clouding of the natural lens inside the eye. Like a camera, the normal eye has a transparent lens that focuses images at the back of the eye. While the camera focuses the image on a film, the eye focuses the image on the retina. If the lens is cloudy, the image on the retina is not clear and vision becomes blurry. There are currently limited medical treatments for cataracts. Updating glasses and increasing light in your environment may improve your vision to some extent, but the cataract will worsen with time. Cataract surgery is the only way to restore vision. That is why cataract surgery is considered the gold standard.
