The eye defect caused by the development of cloudy areas in the lenses is cataract. A cataract is a condition where the natural lens in the eye becomes cloudy, leading to blurred vision, difficulty seeing in dim light, and glare. It usually occurs as a result of aging, but can also be caused by factors such as genetics, injury, or certain medical conditions. Cataracts can be corrected with surgery, where the cloudy lens is replaced with an artificial one, resulting in improved vision.
