The eye lens (also called the crystalline lens) is a transparent, flexible structure located behind the iris and pupil. Its main function is to focus light onto the retina so that clear images can be formed.

Structure of the Eye Lens

• Transparent and biconvex (curved on both sides).
• Made of specialized lens fibers and proteins.
• Enclosed in a thin elastic capsule.
• Suspended by tiny fibers called zonules, which connect it to the ciliary body.

Functions of the Eye Lens

1. Focusing Light
   • Bends (refracts) incoming light rays to focus them on the retina.
2. Accommodation
   • Changes shape to focus on objects at different distances.
   • Becomes thicker for near objects and flatter for distant objects.
3. Maintaining Clear Vision
   • Works together with the cornea to provide sharp images.

Common Lens Disorders

• Cataract – the lens becomes cloudy, causing blurred vision.
• Presbyopia – difficulty focusing on nearby objects with age.
• Lens dislocation – the lens moves from its normal position.

The lens is a crucial part of the eye’s optical system, helping us see objects clearly at various distances by adjusting its shape and focusing light precisely onto the retina.
