LINS
Lens: The Clear Window to the Inner Eye
Description
The lens, a transparent, biconvex structure situated behind the pupil and iris, plays a crucial role in vision. Composed primarily of water and proteins known as crystallins, the lens is responsible for focusing light onto the retina, allowing for clear perception at various distances.
Associated Diseases
Various conditions can affect the health and functionality of the lens:
- Cataracts: The most common eye disorder, cataracts result from the clouding or opacity of the lens, impairing vision.
- Presbyopia: An age-related condition where the lens gradually loses its ability to accommodate for near vision.
- Phakitis: Inflammation of the lens, often accompanied by pain, redness, and blurred vision.
- Lens dislocation: A rare condition where the lens moves out of its normal position, disrupting vision.
