Research explained that our eyes suck

It’s true that our brain is the power house, it’s the cpu and the main controlling system may it be related to eyes, ears or any other body part. But what might be the role of the other body parts on their own? Have you ever wondered your eyes don’t really have some special role to play, especially when compared to some other species that can spot things humans would seriously struggle with. Research has revealed that the way our brains process images from our eyes also leaves something to be desired. Our brains are capable of filtering a constant tsunami of stimuli and piece the important parts together to recreate what we know as reality and it does all this nearly in real time which is really impressive if you think about it. 

Your eyes see objects and observes the color phenomena by color awareness, let’s build an example of a yellow banana. It appears yellow whether you see it in the tungsten light of the kitchen or in sunlight outdoors. Under variety of  conditions, the banana reflects very different light spectra to your eyes, but you see it instead its unchanging material properties. That is, you see that the banana tends to reflect more light in the ‘yellowish’ region of the spectrum compared with other objects, regardless of the spectrum of light shining on all of them, and you conclude that the banana is inherently ‘yellow’. Our visual system is strong enough to take a variable input and otherwise converts it into a stable perception. Size constancy is also a phenomenon where you see the image of a chair on your retina shrinks as you walk away from it, but the chair appears the same size. Your visual system compensates for the changes in the retinal image.

Vision scientists reported color constancy as an important piece to aid object recognition. Without color constancy, color would be an unreliable cue to object identity: your favorite coffee mug would change from pale green to grey at the flick of a switch; your rental car would be unrecognizable in the evening glow. But there is no proof that color constancy is essential for object recognition; the role of color itself, with or without constancy, is not fully understood. Some studies suggest that the super-fast initial stages of object recognition bypass color completely, relying on shape only.
