Question

which helps to focus the light rays on the retina"

Answer 1

eye lens helps in focusing light rays to retina

Answer 2

Answer:

The cornea and lens aid in concentrating light rays on the retina of the eye (retina). Light is absorbed by the retinal cells, which subsequently transform it into electrochemical signals that are sent to the brain via the optic nerve.

Explanation:

The cornea and lens work together to direct light toward the retina of the eye (retina). Properly focus light on the retina, the lens and cornea work together. A layer of tissue at the back of the eye called the retina is light-sensitive, and when light strikes it, specific cells called photoreceptors convert the light into electrical signals.

• Light initially travels through the cornea (the clear front layer of the eye). The cornea helps the eye focus by bending light into a dome shape.
• A portion of this light enters the eye through the pupil (PYOO-pul). The colorful portion of the eye, the iris, regulates how much light the pupil lets in.
• Light then travels through the lens (a clear inner part of the eye).
• The optic nerve carries these electrical signals from the retina to the brain. The visuals you see are then created by the brain from the signals.
• Tears are necessary for your eyes to function properly.
