They’re just sniffing that spice melange.

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.
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.
Plus, no summer day is brighter than a clear winter day with snow on the ground.
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)
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.
But the iris is a mask, it blocks off axis light

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?Wouldn’t this lead to snowblindness? It gets way brighter in the winter
