What causes a loss of transperancy of the lens and can cause blindness?

A loss of transparency in the lens, known as cataracts, is primarily caused by the aging process, which leads to the accumulation of proteins that clump together and cloud the lens. Other factors include prolonged exposure to UV radiation, certain medications (like corticosteroids), and medical conditions such as Diabetes. This clouding can obstruct light from entering the eye, leading to blurred vision and, if untreated, can ultimately result in blindness. Regular eye examinations can help detect cataracts early, allowing for timely intervention.
