@myrrlyn It’s well studied: https://t.co/rEHREkmt7j
@Hair_Artiste We should be able to see in some of the IR freq range that thought to be contributing to healing. "Long wavelength-sensitive visual pigments of vertebrates exhibit maximal absorption at the ∼500- to ∼625-nm range." https://t.co/BH45ashE29
@joachimgoedhart Humans can see wavelengths >1000 nm if the light is bright enough. This phenomenon was first studied in the 1940s. Here’s a recent paper: https://t.co/dTUIyJ4C4q

@lemonodor @_Zam15_ @thenewarea51 So there’s a difference between sensitivity and resolvability. As mentioned, the human eye can actually be “sensitive” to coherent laser light up to 1,025 nm and ppl can see it if all other light is filtered out and said l
@lemonodor @_Zam15_ @thenewarea51 In fact, directing a laser using collumnated coherent light directly in one’s eye can apparently induce a photochemical response in rod receptors up to 1,025 nm if directed directly into your eye. Especially with all other

@AstroKirsten Light = only visible? But to who or what? Lots of living creatures can “see” light, and a lot of it, other than people can see down into the infrared and up into ultraviolet, and also ... https://t.co/wDPHDqx73R
@AstroKirsten Well, I suppose some humans can see UV and maybe even infrared, under certain circumstances? (https://t.co/GIES6lgjA6) So, maybe it's not *that* weird to call those light 😜

Apparently, we can see infrared, if two infrared photons nonlinearly combine in our retina and transfer a total energy close to the energy of a green photon. Article: https://t.co/vl5LfQAwlH Paper: https://t.co/ROngssDgPn https://t.co/UK9gCARTHo
@lukesjulson @breakliquid @klaragerlei @martin_a_vinck These folks measured human behavioral sensitivity to IR laser pulses (so no leakage), and it looks like there's something going on there in the 10 -100 µW range. https://t.co/qWOz0Nda0O https://t.co/

@JeanLaurensLab @apeyrache @DWSullivanJr https://t.co/A2OJ96tSfz Looks like they can still see in infrared led illumination But there is also two photon vision in primates so 1000 is not safe either 😉 https://t.co/r00QInjXNI
@ID_AA_Carmack But people *can* perceive IR illumination, especially when there are rapid pulses of it hitting the eye in succession. The mechanism "halves" the frequency so 1000nm looks "greenish." This "two photon" mechanism is also key for building mi
