In a healthy eye, the lens is transparent and focuses light on the retina. Over time, the lens can slowly lose the ability to let light into the eye as it becomes cloudy. A cataract is a simply lens that becomes opaque over time. When severe, the cataract must be removed because it prevents light from entering the eye and decreases vision. In the worst cases, the patient can be nearly blind due to cataracts.
