Crystalline lens adjustment
Crystalline lens adjustment
The crystalline lens changes shape to focus light onto the retina for clear vision at various distances.
Why lens shape change?
Why lens shape change?
The lens changes shape to adjust the focus of light for objects at varying distances, ensuring sharp vision.
