The light coming from an object enters the eye through:a)cornea and pupilb)Pupil and retinac)iris and pupild)cornea and irisCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Light rays enter the eye through the cornea, the clear front “window” of the eye. The cornea's refractive power bends the light rays in such a way that they pass freely through the pupil the opening in the center of the iris through which light enters the eye.

Answer

Cornea and iris

Answer

THE light coming from an object enters the eye through cornea and pupil  because the front part of eye is cornea and just  behind  the cornea is the Iris.... it is Flat,,,,,;colour ring shaped membrane behind the corner of the eye there is a hole in the middle of the areas which is called PUPIL of the eyes.

Answer

Explanation:

The process of vision involves the eye receiving light from an object and then converting it into nerve impulses that can be transmitted to the brain. The light enters the eye through the following structures:

1. Cornea: The cornea is the clear outer covering of the eye that functions as a protective layer. It is responsible for refracting or bending the incoming light rays.

2. Pupil: The pupil is the circular opening in the center of the iris. It regulates the amount of light that enters the eye by dilating or constricting in response to changing light conditions.

3. Lens: The lens is a transparent structure located behind the iris that further refracts the light and focuses it onto the retina.

4. Retina: The retina is a thin layer of tissue that contains photoreceptor cells called rods and cones. These cells convert the incoming light into electrical signals that are transmitted to the brain via the optic nerve.

5. Optic Nerve: The optic nerve is a bundle of nerve fibers that carries the visual information from the retina to the brain, where it is processed to form the perception of an image.

Therefore, the light coming from an object enters the eye through the cornea and pupil, which are the first two structures that the light encounters.
