A sensitive organ that allows us to see the world and colors around us.

The lens in the human eye focuses light onto the retina to form images.

A light-sensitive screen at the back of the eye where images are formed.

The transparent bulge at the front of the eyeball that helps refract light.

A dark muscular diaphragm in the eye that controls the size of the pupil.

The opening in the iris that regulates the amount of light entering the eye.

Bending of light as it passes through different mediums, like the cornea and lens.

Provides finer adjustments to focus light on the retina at varying distances.

Visual effects related to light, such as rainbows and the blue color of the sky.

The human eye is approximately spherical with a diameter of 2.3 cm.

The lens in the human eye helps focus light onto the retina for clear images.

Light enters the eye through the cornea, the transparent front part of the eyeball.

The cornea refracts light before it passes through the lens to the retina.

The iris controls the size of the pupil to adjust light intake.

The pupil is the opening that regulates light entering the eye.

The retina is the screen where images are formed from focused light.

The crystalline lens fine-tunes focus for objects at various distances.

The human eyeball is approximately spherical, about 2.3 cm in diameter.

Includes effects like rainbows and the blue color of the sky caused by light refraction.

The human eye is a highly sensitive organ, crucial for vision and experiencing color.
