crystalline lens
Focuses light internally
The crystalline lens is the transparent, flexible structure inside the eye that focuses light onto the retina.
It sits behind the iris and changes shape to adjust focus between near and distant objects—a process called accommodation.
With age, the crystalline lens hardens and clouds, causing presbyopia and cataracts.
Often shortened to simply lens in medical contexts.
