The Human Machine Mystery 2

The cornea is the clear layer over the eye that acts as a protective layer and helps to focus light onto the retina.

If the cornea is cloudy, vision is impaired, and one can only distinguish between light and dark.

The colored part of the eye is called the iris.

False.

The retina.

The iris controls the size of the pupil and thus regulates the amount of light that enters the eye.

The pupil is the opening in the center of the iris that allows light to enter the eye.

Light enters through the cornea, passes through the pupil, is focused by the lens, and then hits the retina.

The lens focuses light onto the retina, allowing for clear vision.

The retina contains photoreceptor cells that convert light into electrical signals sent to the brain.
