What do you already know about the functions of the eyeball?

Anatomy of the Eyeball

The eyeball is a complex structure composed of the cornea, iris, pupil, lens, retina, and optic nerve.

Function of the Cornea

The cornea is the clear, outermost layer that helps focus light into the eye.

Role of the Iris and Pupil

The iris controls the size of the pupil to regulate the amount of light entering the eye.

Lens and Focusing

The lens adjusts its shape to focus light onto the retina, enabling clear vision at different distances.

Retina and Visual Perception

The retina contains photoreceptor cells that convert light into electrical signals for the brain to process images.

Optic Nerve and Signal Transmission

The optic nerve carries visual information from the retina to the brain for interpretation.

Vision Disorders

Common vision problems include myopia (nearsightedness), hyperopia (farsightedness), and astigmatism.

Eye Health and Care

Proper eye care, regular check-ups, and protection from harmful UV rays are essential for maintaining good vision.

The Importance of Eyeball in Daily Life

The eyeball plays a vital role in daily activities such as reading, driving, and experiencing the beauty of the world.

Eye Safety Measures

Wearing protective eyewear during sports, avoiding eye strain from screens, and handling chemicals carefully are crucial for eye safety.
