Filter Infrared Infra
Infra-red vision, is it possible?
I’ve read somewhere that if one walks around wearing goggles that filter al visible light but lets infra-red light (or perhaps it was UV…can’t remember for sure) one would eventually become able to see infrared radiation as well, is it true? and if so, any requirements besides walking around with said goggles? if not, why is it impossible?
btw, is this the right category for this question?
If a human starts out not being able to see infrared light, nothing short of replacing the cone cells in their eyes with new ones that have a different structure will allow them to see infrared light.
We’re talking about a genetic mutation that causes the retina to produce new cone cells of a type it had never produced before. Exposure to infrared light will not cause such a mutation, since it would require DNA to be altered.
That being said, different humans have different limits on the spectrum their eyes can perceive.
