Some modern TVs add as much as 150ms! Light passes through the cornea, ... Six bands of muscles attach to the eyeball to control the ability of the eye to look up and down and side to side. These are images that are encoded in random patterns, previously thought only detectable by computer. Although the human eye has a focal length of approximately 22 mm, ... Away from the center, our visual ability decreases dramatically, such that by just 20° off-center our eyes resolve only one-tenth as much detail. It can detect "ghost images." The lens of a camera sits in the very front of the camera and is visible; a human lens is inside the eye. Why didn't we develop eyes in the back of our heads? The cornea bends light toward the pupil, which controls the amount of light that hits the lens.

While an average human reaction time may fall between 200-250ms, your computer could be adding 10-50ms on top. That reflected light enters the human eye first through the cornea, the outermost part of the eye. While an insect compound eye has the capability to see color if it contains corresponding sensor cells, most insects can …

The lens then focuses the light on the retina, the layer of nerve cells in the back of the eye… Why didn't ants evolve to glow in the dark?
