Why is it when I look at something that’s “Glow in the Dark” it appears to be dim, but when I see it in my peripheral, it shines like a damn lighthouse?
Phospherescent (glow in the dark) things emit very small amounts of light. The human eye is structured with a very high concentration of *cones* in the middle-section (fovea centralis) of the retina at the back of the eye. These pick up colour and can resolve things that you're looking directly a…
The Short Answer
Phospherescent (glow in the dark) things emit very small amounts of light. The human eye is structured with a very high concentration of *cones* in the middle-section (fovea centralis) of the retina at the back of the eye. These pick up colour and can resolve things that you're looking directly at in great detail (up to a resolution of roughly 1 cm at a distance of 100 metres). The *rods* which are mostly found on the outer parts of the retina only transmit monochromatic information, but can pick up much lower levels of light. This gives rise to the phenomenon of individual stars being clearly visible to an observer in their peripheral vision, but of them becoming invisible as soon as the person looks directly at them.
