Now as for shapes that you see in static, only one can say. You may be seeing actual "waves" of photons as they bombard the rods, or the rods may
be receiving visual information that photons are being blocked by "objects" that can't be seen in our visual spectrum... oooooohh =). Also,
"seeing" blues and purples would not be to surprising, if you think about it. Being in low to no light, your cones might pick up some low wave EM
wave registering in the blues and purple... the low end of our visible EM field.
Pretty cool aye?? Also, the problem with rods, is that they do not have the ability to pick up small to fine detail, just general, overall detail.
Now, why such a long discussion on how light is received by the brain!! Well, the rods and the cones are central to seeing auras and being able to
exercise your rods and cones is key. This is not a plug for a book or anything, but I bought this book about 15 years ago and did it's exercises and
it worked!!! But of course when you don't exercise a muscle. Unfortunately, I can't find the book, I think it's...
