The human eye is a complex and fascinating organ that enables us to perceive the world around us. Understanding its structure and function is crucial for Class 10th Biology students.

Structure of the Eye:

The eye consists of several key parts, each with a unique function ¹ ²:
*Cornea*: The transparent, dome-shaped surface at the front of the eye that refracts light.
*Iris*: The colored part of the eye that controls the amount of light entering the eye by adjusting the size of the pupil.
*Pupil*: The opening in the center of the iris that allows light to pass through.
*Lens*: A transparent, flexible structure behind the iris that changes shape to focus light on the retina.
*Retina*: The innermost layer of the eye containing photoreceptor cells (rods and cones) that convert light into electrical signals.
*Optic Nerve*: Transmits visual information from the retina to the brain.
*Sclera*: The white, opaque part of the eye providing protection and structural support.
*Conjunctiva*: A thin membrane covering the front of the eye and lining the inner eyelids.

Function of the Eye:

The eye works by ³ ¹:
1. *Light Refraction*: Light enters the eye through the cornea and pupil, and is focused by the lens onto the retina.
2. *Signal Conversion*: Photoreceptor cells in the retina convert light into electrical signals.
3. *Signal Transmission*: The optic nerve transmits these signals to the brain, where they are interpreted as visual images.

Importance of Diagrams in Paper Solving:

Diagrams play a vital role in understanding and solving questions related to the human eye. They help to ⁴:
Visualize the structure and function of the eye
Illustrate complex concepts, such as refraction and accommodation
Identify and label different parts of the eye
Solve problems related to vision defects and corrections
