Question

How do we see what we see?

Answer 1

Eye:

1. The eye is a spherical, jelly-filled organ found in vertebrates.
2. It is housed in a bone chamber in the skull and includes a lens that directs light onto the retina.
3. One of the body's most sophisticated sensory systems is the eye.
4. Every component of the human eye, including the muscles, tissues, nerves, and blood vessels, is responsible for a specific action.

Working of an Eye:

1. The Cornea performs the role of a window to the human eye.
2. A significant amount of the refraction that enters our eyes is caused by the cornea.
3. It makes up the transparent front surface of the human eye.
4. Additionally, it stops outside materials from getting inside the eye.
5. Directly behind the cornea is where you'll find the iris.
6. It is in control of the pupil, an aperture that circles the eye.
7. It controls how much light enters the human eye, similar to an automatic camera shutter.
8. The light rays entering our eyes are further focused on by crystalline lenses.
9. Once more, we can make a comparison to the operation of an autofocus lens in a camera.
10. The eye's capacity for accommodation is what is meant by this.
11. The lens tries to focus on the object depending on its location.
12. The bulk of the eye's inner chamber is filled with a jelly-like substance called vitreous humor.
13. It aids in the eye's continued spherical form.
14. After passing through the aperture, the light rays pass through the vitreous humor before impacting the retina.
15. The retina is the inner, light-sensitive layer of the human eye.
16. The retina should receive light rays that are focused, creating a picture.
17. The choroid and the sclera are also part of the inner tissue, which also has this lining as its outermost layer.
18. When light strikes the retina, the optic nerve sends a signal electrically to the brain.
19. The brain then processes the image, and eventually, we see what we see.
