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.

[-] Donut@leminal.space 51 points 2 months ago

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

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.

[-] Suru@mander.xyz 7 points 2 months ago

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)

[-] rhombus@sh.itjust.works 1 points 2 months ago

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?

[-] lemonmelon@lemmy.world 18 points 2 months ago

But did you know
That when it snows
My eyes become violet
And light that you shine
Can be seen?

[-] MrShankles@reddthat.com 8 points 2 months ago

BAAABBAAAYYY! I compare you to a kiss from a deer on the rein

[-] Boxscape 11 points 2 months ago* (last edited 2 months ago)

Reindeer's are golden in summer but turn deep blue in winter

Gold and blue?
My dude, those eyes are black and white. 😏

[-] chicken@lemmy.dbzer0.com 10 points 2 months ago

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

[-] lowleveldata@programming.dev 14 points 2 months ago

They wear sunglasses when it's too bright, duh

[-] ninja@lemmy.world 13 points 2 months ago

In the polar regions there are extended periods of wintertime where the sun does not rise.

[-] hsdkfr734r@feddit.nl 8 points 2 months ago* (last edited 2 months ago)

Looks like brown and purple to me.

Edit: TIL. It reminds me of the Moor frog, which turns blue... ish when horny.

[-] plinky@hexbear.net 3 points 2 months ago

TFW you don't have autumn eyes to see blue color πŸ™

[-] hsdkfr734r@feddit.nl 3 points 2 months ago* (last edited 2 months ago)

I don't get it. What do you want to say?

The Internet replied with this:

Umm... and I'm lost. :)

[-] plinky@hexbear.net 2 points 2 months ago* (last edited 2 months ago)

Tis a joke about color perception :) to me, in the photo the eye does look like oversaturated blue (maybe due to blown out white around the eye)

[-] teletext@reddthat.com 3 points 2 months ago

Both images are heavily edited. With different filters. Any assumption about their real colors is moot.

OK. I suspected something like this.

Colour perception, different display... who knows. :)

The shape of the iris changes drastically too

LISAN AL GAIB!

[-] Cadeillac@lemmy.world 5 points 2 months ago

TIL my poop is gold

[-] AsudoxDev@programming.dev 3 points 2 months ago

Isn't that more like dark violet?

[-] Kallioapina@lemmy.dbzer0.com 2 points 2 months ago

Blue? That colour is violet in my eyes.

[-] affiliate@lemmy.world 2 points 2 months ago

damn i wish my eyes did that
