I was looking for information of the rods and cones and the parts of the light spectrum they "see". I was wondering if the rods can "see" into the ultraviolet and infra-red.
For example, the cones are colour-sensitive and according to the medical texts there are three types corresponding to red, green and blue. Orange light stimulates both red and green cones. That gives us the usual colour spectrum of red, orange, yellow, green, blue, indigo, and violet.
Whereas the consensus seems to be that the rods can only detect the amount of light hitting them. So, someone with only rods would see the world in black and white.
The question of do the rods "see" into the ultraviolet, is something I have no answer for. Perhaps someone who can answer the question might chime in?
That said, here is an interesting, for me at least, point to consider.
Ordinarily, our eyes are drawn to objects that are brighter than the background. For example, when we look at a tree in daylight, we habitually focus on the green leaves, and not the shadows between the leaves. We also focus on colour rather than the black and white in a landscape.
So we have to make an effort to train our vision to notice the shadows.
Now, most shadow people sightings are said to be seeing shadows out of the corner of the eye. That is the peripheral vision. So we need to take movement into account, as our peripheral vision is very sensitive to movement.
That said, I have one young lady who visits here who can see the shadow people by looking straight at them in daylight. The young lady doesn't like dark corridors and always sleeps with a bright night light. That suggests to me her eyes (rods) are more sensitive to movement than normal, or perhaps she simply never lost the ability to see the shadow folk from early childhood.
I should ask her if she is colour-blind. When she draws the shadow folk, she always draws them in black and white.
Which, I guess, brings us to the subject of dicyanin glasses . . .
