Science textbooks say we can’t see infrared light. Like X-rays and radio waves, infrared light waves are longer than the light waves in the visual spectrum. But an international team of researchers co-led by Frans Vinberg, PhD, (left) and Vladimir J. Kefalov, PhD, has found that under certain conditions, the retina can sense infrared light after all.
I had just assumed those were supposed to be visible. Like the lights the Xbox Kinect had.
But if they aren’t, that’s annoying lol. Same deal with hearing the high pitch frequency old CRTs would emit.
The CRT thing is pretty common I think, you just lose your high frequency hearing as you age.
Yeah, I was using it as an example of annoying things fitting around the same niche lol.
I lost it at a Cypress Hill concert
Its not intentional as much as it is a cost savings
