Question

describe briefly how the human eye sees the object

Answer 1

The human eye refracts light emitted off objects and onto the retina to bring the objects being viewed into focus. This involves many functions and processes.
 
Step 1: 
Light rays pass through the eye’s clear front cover called the cornea. 

Step 2: 
Light passes through the eyes pupil, the eye’s window to the world. The pupil is surrounded by a sphincter call the iris; the eye’s colored ring.

Step 3: 
Light passes through the eye’s crystalline lens, which constricts to help light rays come to focus at one focal point.

Step 4: 
Light rays travel to and come to rest on the retina resulting in clear vision.

Step 5: 
Once light rays come to rest on the retina a signal is carried done the optic nerve to the brain.

Step 6: 
The brain receives the signals and interprets them into a picture(s).

Step7: 
The brain tells the eyes what it sees by forming the picture.

Answer 2

there is some parts of eye
1) iris- it cobtols the amount of light entering into eye and as per adjust the pupil..
2) ciliary muscles-it relaxed the contracted lens.
3) retina-send optical image to brain via optic nerve.
4) cornea-it protects internal parts of eye.
