Some scientists believe that the retina has receptors similar to that of an RGB red, green, blue color spectrum monitor. These colors are then differentiated by our brain which tells us to see red colors.
The study that led to such a remarkable discovery was performed under ideal conditions where participants were allowed to adapt to total darkness; flashlights of nanometer blue-green wavelength, acted as a stimulus, to which the human eye is most sensitive.
It was concluded that our brain interprets vision when the retina is exposed to 5 — 14 photons. The human eye perception is limited to a certain degree. We are only able to see colors between to nanometer wavelengths. This is why we are not able to perceive ultraviolet and infrared colors. Ultraviolet colors fall in shorter wavelengths than nanometers, whereas infrared colors are longer than nanometer wavelengths. For example, when you take a look at bananas, you see the color yellow because they bounce off color wavelengths of nanometers, when hit by full spectrum light.
Have you ever asked yourself why you see things in 3D? Our brain is responsible for reconstructing images which let us experience life from a 3D perspective. This is because we have a pair of eyes that gives birth to a phenomenon known as Binocular Disparity — a slight difference in perspective between the left and right eye.
Binocular disparity plays a vital role in giving depth to a scene. Convergence is another phenomenon which signals the brain to create depth of field, particularly when you are focusing on something close to your eyes. It takes time for the human eye to perceive visual depth of a scene. The brain of a newborn child is not fully developed and must adapt to the new environment first before learning to construct a three- dimensional perspective.
A study on infants has revealed that it takes a two months old baby to construct depth awareness of an image. The neural pathways of the brain recalibrate themselves chemically to turn on scotopic vision circuits. These circuits are normally off during the daytime and require 20 minutes of darkness to be active. Scotopic vision circuits do not adapt to colors other than blue, as their receptors are blue-sensitive. You might have noticed how everything tends to take a bluish hue when you are trying to see in the dark.
Ever thought why you can see the stars twinkling and shining at night? The brain is the main asset behind our visual perception. The eyes are merely tools to perceive light and transfer it to receptors that signal the brain to form images.
This organization seeks to present things in writing as they actually are in their locations. Unlike with chronological order and other organizational methods, spatial entirely focuses its descriptions on the location.
