Answer 2

The human eye is an organ that reacts with light and allows light perception, color vision and depth perception.

Key Points

• The eye is made up of a number of parts, including the iris, pupil, cornea, and retina.
• The eye has six muscles which control the eye movement, all providing different tension and torque.
• The eye works a lot like a camera, the pupil provides the f-stop, the iris the aperture stop, the cornea resembles a lens. The way that the image is formed is much like the way a convex lens forms an image.

Key Terms

• pupil: The hole in the middle of the iris of the eye, through which light passes to be focused on the retina.
• aperture: The diameter of the aperture that restricts the width of the light path through the whole system. For a telescope, this is the diameter of the objective lens (e.g., a telescope may have a 100 cm aperture).

The human eye is the gateway to one of our five senses. The human eye is an organ that reacts with light. It allows light perception, color vision and depth perception. A normal human eye can see about 10 million different colors! There are many parts of a human eye, and that is what we are going to cover in this atom.
