Infrared Lense or Ultraviolet Lense?

Question

I bought a set of whats claimed to be IR Glasses, but it turns everything blue/purple. Even the lense says its UV 400.

No doubt, it doesn't let visible light through as it only permited a red LED on my microwave, but not the Green LED at the same brightness.

So, can some 1 tell me if this is IR or UV.

Descriptions:
When i look at a light bulb ( white-yellow to pink/purple)
Moon (White to blue purple)

Thanks

Answer 1

Your question contains 2 separate questions: a million. The chemistry of human creative and prescient: "The retina contains 2 varieties of photoreceptors, rods and cones. The rods are greater different, some one hundred twenty million, and are greater delicate than the cones. even although, they don't look to be delicate to coloration. The 6 to 7 million cones supply the attention's coloration sensitivity. The experimental info potential that between the cones there are 3 categories of coloration reception -- cones that are delicate to blue, cones delicate to eco-friendly, cones delicate to blue. those are chemical sensitivities (not wave-length sensitivity like our listening to), similar to the three coloration-delicate layers in coloration action picture." 2. The evolution of human creative and prescient: We human beings developed in a wooded area putting, with a lot of eco-friendly leaves. Human creative and prescient is maximum delicate to eco-friendly colorations. Our survival depended on differentiating poisonous from nutritious fruit -- bright yellows, oranges, and reds -- hidden under eco-friendly leaves. We human beings can not extract lots foodstuff from pollen, so UV creative and prescient does not supply an evolutionary benefit (to compete with bees for their favorite nutrients source). Infrared sensitivity = warmth sensitivity. If we've been snakes, shall we hunt at nighttime, employing our IR creative and prescient to "see" mice etc. even although, we human beings are actually not nocturnal, and we don't have the fast reflexes of snakes, so we can't effectively compete with snakes for their favorite nutrients source. The evolutionary theory is: A species that evolves to "do one difficulty nicely" -- make the main of one particular visible variety to make the main one particular nutrients source -- will win in a contest with species that have developed to do many stuff (make the main many nutrients components) poorly.
