Document Summary
Transmitting information to the primary visual cortex. Human visual system is a remarkable system capable of transforming an upside down 2d retinal image into the 3-d world that we perceive. What we see isn"t the same thing as what we are in reality looking at. It is instead a metal representation constructed by our brains based on the information it receives from our eyes. The human eye can only see a small portion of the electromagnetic spectrum. Humans can see light between 380 and 760nm (nanometers). Everything outside of that range is beyond our ability to perceive. Iris = contractile tissue that limits the amount of light that passes through the lenses to the retina. Pupil = hole in the retinal that allows light to enter the eye detect the presence of a dimly-lit object) and acuity (the ability to see the details of the object).
