So, just finished reading an article on WaPo about fireflies/lightening bugs and got me thinking further… Car headlights suck. They mess up our night vision when we pass another dickhead running white/blue lights. We mess up the habit(at) of many animals/bugs. So why not red lights? My hiking/camping headlamp has a red light option, which is the only function I use, and I can see fine. Why the FUCK do we still have these ungodly bright white/blue lights?
Actually, you can’t “see fine” with the red lights. Sure, once your eyes adjust to the darker light, you can see at some level. But the red light doesn’t allow you to see anywhere near near as well as you can in a white light. also, if you have poor night vision, red light isn’t very good at all. And, the biggest reason why you can’t use red headlights is color blindness. There are people who would be completely in the dark with those headlights.
That’s… Not how color blindness works.
As a colorblind person red light still works for me
How early did you sign up to get this username. Awesome
Usernames are only unique per instance. So it’s easy to get any name you like on smaller instances.
Aha thanks, of course. Still learning over here lol
Yeah. I was so stoked when I got this name before I learned how it all worked
Hmmm for some reason it says my username is Lemmy on some instances I’ll have to fix that
Isn’t there some specific color blindness that would make people unable to see reasonably under red light because they lack red cones and the other cones aren’t sensitive enough at that wavelength, so they’d effectively be seeing like a normal sighted person would see with only 10-20% of the light that’s present?
Shouldn’t affect the area outside the fovea since there are also rods but that’s not too helpful.
