If so our eyes should be burning because of the lights that we obsorb each day
the lights should transfer its energy into our eyes and causes our eyes to heat up and eventually burn?
Idk, just wondering lol
I'ts not a stupid question...at least I've never heard it asked before, so why should you not post it?
Anyway, the light coming into our eyes will not burn the retina for two reasons:
1) It's not energetic enough to burn at the levels it normally receives from ordinary sunlight (but be on the watch for lasers...even laser pointers have sufficient intensity to cause damage and you won't feel it as it's happening.)
2) Beyond whatever transfers the energy from the retina to the optic nerve the eye will respond to the light as a source of heat and the body will regulate that before any damage is done. (Again, watch out for lasers. They have too much intensity for the eye to easily regulate the heat.)
I've actually have had laser surgery on both eyes and I can verify that there is no pain despite the fact that the surgery was meant to burn out portions of my retina. On the other hand the intensity was well beyond the comfort range and I have no desire at all to repeat the experience.
I'm a "something shiny" kind of...Oh look! Something shiny!
