Seeing, of course, is done by the eye. But our brain plays a very important part of the process we call seeing. Mechanically, this is what happens. Light waves pass through the pupil of the eye and form an image on the retina. The retina is a carpet-like screen of cells at the back of the eyeball.
Each of the retina’s 130,000,000 cells is sensitive to light. When tight strikes a cell a chemical change takes place. This starts an impulse in a nerve fiber, which travels through the optic nerve to the seeing portion of the brain.
But this is not all that happens. What the brain sees is very different from the pictures formed on the retina. For example, your eyes are seldom at rest. Ir you stand outdoors looking at the scene around you, your eyes stop for only a second at the grass, treetop, cloud, bird, or squirrel.
The brain does not ste a series of quick snapshots. The seeing part of the brain records each picture and remembers it. It adds them together and gives them meaning, so that the whole picture is seen, not the parts, In a second, it draws upon the store of memories in the brain. A tree, a cloud, a squirrel—these have been seen before. It takes only a glance to recognize them.
So seeing includes the use of many parts of the eye, the optic nerve, and the parts of the brain that see and interpret the eye’s messages. That’s why a baby must learn to use his vision. Before long his visual mechanics work well. But his vision is still poor. Why? Because he understands little of what he sees. The brain is not yet playing its full part in seeing.
Do We See With Our Eyes Or Brain?
Our eyes do a really good job of capturing light from objects around us and transforming that into information used by our brains, but our eyes don’t actually “see” anything.
What part of the brain helps us see?
Answer- Occipital lobe.
What part of the brain controls the 5 senses?
Answer- parietal lobe.
What side of brain controls balance?
Answer- cerebellum. It controls balance, movement, and coordination.
Answer- Out of all the five senses, your vision seems the most important
