Theyβre just sniffing that spice melange.
Source of Nokotan's powers revealed. The spice must deer
This is how they gain magic flight at Christmas time
This doesn't make sense to me. The iris doesn't collect light for vision. The pupil expands or contracts to vary the amount of light that reaches the retina. Iris color should have nothing to do with it.
From the first source on the linked study, they describe it as the following:
(...) This functions as a mirror providing the second opportunity for photon capture by reflecting light back through the retina, enhancing visual sensitivity.
Neat!
But the iris is a mask, it blocks off axis light
Plus, no summer day is brighter than a clear winter day with snow on the ground.
It is if you live in a part of the world that is dark for months at a time during the winter, like reindeer do.
Most reindeer live North of the Arctic Circle, where the sun does not rise above the horizon in winter months. I suspect most summer days are brighter than the few hours of twilight the reideer get in December.
The pupil dilates, combined with more uv light seasonally, changes the structure of the iris and thus it's color. (It reflects differently)
A lighter iris color correlates with higher light sensitivity and better low light vision. The higher density of pigment in a darker iris blocks light better.

TL;DR: Eyes with lighter color irises have better low light performance in at least some circumstances.
Did you just teal deer a reindeer article?
But did you know
That when it snows
My eyes become violet
And light that you shine
Can be seen?
BAAABBAAAYYY! I compare you to a kiss from a deer on the rein
Wouldn't this lead to snowblindness? It gets way brighter in the winter
They wear sunglasses when it's too bright, duh
In the polar regions there are extended periods of wintertime where the sun does not rise.
Reindeer's are golden in summer but turn deep blue in winter
Gold and blue?
My dude, those eyes are black and white. π
Looks like brown and purple to me.
Edit: TIL. It reminds me of the Moor frog, which turns blue... ish when horny.
Same, bro
So that's where marbles come from!
The shape of the iris changes drastically too
TIL my poop is gold
Isn't that more like dark violet?
damn i wish my eyes did that
Blue? That colour is violet in my eyes.
Fucking Mary Sues...
