Hey guys, I was just in a discussion about this very subject. It turns out that some people believe that humans with blue eyes have special powers that let them see colors on a much wider spectrum and that their blue eyes give them night vision. Is there any scientific basis for this or is it just pseudo-scientific nonsense?

If blue/gray/green eyes didn't come with any benefits over brown/black eyes, why did the mutation spread instead of dying out?
Grayson Clark
It's not that it has benefits, but it stopped being a drawback in a region with less sub exposure.
Blue eyes are more sensitive to sunlight, that's all.
Brody Gray
the color of the iris has no effect on the quality vision op.
just lok up a simple wiki page of the eye

Ice blue eyes are insane.
Isaac Baker
Sensitivity to light implies better vision. Blue eyes also have the benefit of being widely regarded as beautiful, which is a boon since sexual selection is a very real thing.

>blue eyes give night vision
Ignore them/yourself op, that's completely retarded.
If you want night vision as a human you will have to go colorblind and hope the genes involving it go into extra brain processing into sensitivity at low light. Just like the micronesians in Pingelap.

It doesn't, it implies that your retina is getting fried.

>being able to percieve smaller fluctuations in the light that reach your eyes doesn't imply better vision
Maybe we're thinking of two different things when we say "sensitive"?
Blue eyes being of no benefit also makes you wonder why certain ethnic groups ended up being 60-80% blue eyed. Why would a recessive gene be so widespread without providing any benefit?
Xavier Scott
>Maybe we're thinking of two different things when we say "sensitive"?
Yes, blue eyes are 'more sensitive' to light because of the lack of melanin that would normally protect the retina.
answered your other question, probably.

Less pigmentation in the iris means better color vision, whilst more pigmentation means more accurate vision in strong light. From here, it's not difficult to try and reason as for why certain eye colors are more common in certain parts of the world. Dark eyes give better vision in areas where there's strong sunlight while lighter eyes are better at distinguishing colored objects from a homogenous background.
Blue eyes simply couldn't be so widespread if they lacked a niche over dark eyes. 80% of certain groups being blue eyed is just way too high a number for that to be the case.

You seem upset. Do you have brown eyes?
Carson Lopez
A way above average number of successful military sharpshooters have blue eyes, for what it's worth.
Dominic Young
I'm just glad I don't have poop colored eyes ahahahaha
Daniel Edwards
I have green eyes. Still, your reply makes no sense.
No idea what the first one is about, second one seems interesting but it means the color of the iris is an indicator for the macular pigmentation, the color of the iris itself makes no difference to vision. Also what I said is still true. Maybe blue eyes are a byproduct of adaptation rather than the adaptation itself, unless the first paper says something I'm not getting.
Liam Scott
That's some really cool shit. Neither links are journals but it makes sense the brain would compensate in some way and again the result is really neat.
Nathan Price
ITT poop eyes trying to prove they are equal to blue ones
Yeah, blue eyes master race.
Jonathan Anderson
>Blue eyes simply couldn't be so widespread if they lacked a niche over dark eyes.
Not true, inbreeding, distance/isolation from other populations, sexual selection and disease could all be factors of prevalence.
As a matter of fact the pleague could have easily increase prevalence of blue eyes by the manner of how it spread and who it affected.

Considering who got affected first and dealt with the longest the plague could have lasted and hit europeans with darker color eyes much harder.

>blue eyes master race
Given that the only significant difference in blue eyes in terms of practical application (their sensitivity to bright light) is a bit of a drawback...
Connor Murphy
>Eye Pigmentation and Vision
have nothing to do with each other. Light eyes are "more sensitive to light" as in they will develop cataracts before a dark eyed person. They have less protection in the iris and they stuck around because, as we do with diamonds and gold, they are aesthetically pleasing, which is the primary concern when finding a mate.
You will try to inflate the scientific reasoning to be some superiority this-and-that because you're uneducated and inferior, as in your brain power is low and you are inefficient mentally. You have no evidence for your claims, so nobody cares about why you think something is.

The myth comes from the idea that the color of the iris scatters light differently before it enters the pupil. There's a species of reindeer where their eyes change to blue during dark winter months which increases their night vision, and some people seem to think that human eye color works in the same way.
