Density of the lens changes with age: which statement is correct?

Explanation:
As people age, the lens undergoes biochemical changes that make its tissue more compact and less transparent. Crystallin proteins tend to aggregate and cross-link, and water content shifts, especially in the nucleus, leading to increased optical density. This rise in density is what you see as age-related lens changes, including nuclear sclerosis and a higher likelihood of cataract formation, which reduces clarity. The lens does not become less dense, stay constant, or disappear with normal aging, so those statements aren’t accurate.
