These fissures cause light to scatter when hitting the retina, often causing issues with glare. When the lens gets cloudy, it reduces the amount of light entering . Nuclear cataracts form in the middle of the lens and cause the nucleus, or the center, to become yellow or brown. This . This disease affects the lens of the eye, causing a loss of eyesight. Unlike nuclear sclerotic cataracts that affect the center of the lens, cortical cataracts affect the outer layer of the lens.
