The crystalline protein structure that allows focusing in early life and may become cloudy with age is known as what?

The lens is the focusing structure of the eye. It is made of crystalline proteins that keep it clear and flexible, allowing it to change shape to focus light onto the retina, especially during close vision in early life. As we age, these crystalline proteins can degrade and clump together, causing the lens to become cloudy—a condition known as a cataract. This cloudiness reduces vision but can often be treated by replacing the cloudy lens. The cornea helps with the eye’s initial focusing, the iris controls pupil size, and the retina is the light-sensitive layer at the back—each with a different role, while the lens provides the adjustable focus through its crystalline proteins.
