What happens to the lens of the eye in cataracts?

In cataracts, the lens of the eye becomes cloudy due to the accumulation of proteins that clump together and disrupt the lens's clear structure. This clouding interferes with the passage of light into the eye, leading to blurred or dim vision and, if untreated, can result in significant vision impairment. The clarity of the lens is essential for proper vision, as it helps to focus light onto the retina. Therefore, the development of cloudiness is a characteristic feature of cataracts and is directly responsible for the visual disturbances experienced by individuals affected by this condition. The other choices do not accurately describe the changes that occur in the lens during cataract formation.
