Scientifcally speaking is it true that people with very bright eyes are more sensible to daylight but see better in the dark?

>bright eyes are more sensible to daylight
I have sensitive shoes.
>>
>>17082153
No. We just do better on snow and water
>>
>>17082153
Yes. If you have blue eyes you will be perma squinting outside on bright days without sunglasses.
>>
>>17082153
Blue eyes just have less UV protection.
>>
No one knows what it's like.
>>
>>17083089
But bluer things reflect UV instead of absorbing it.

>"How do I get eyes like that?"
>>
>>17082153
No, there is no evidence of this. People need to stop thinking every little thing has some deep purpose for the body. Traits can also spread through other means like genetic drift or sexual selection.

This is how you cope with being genetically inferior btw.

This is how you cope with being a terminally online depressed retard, btw.

I tested this with my wife. I have brown eyes, my wife has light blue eyes. Her pupils always look larger than mine at any light level. But when the lights go out it seems like I can see slightly better than her. Also she wears glasses and I don't. But with her pupils always being larger, you'd think she would have better night vision. I don't know why my pupils are always small, even in low light.

30seconds direct sungaze from deck at noonish if possible while maintaining front dark curtains with sunlight still coming into both rear bay window kitchen and dining room patio doors gives less bright time at higher intensity with more dimmer or abyss time at lower intensity. I wonder how this compares to people who lives in caves? I wonder how many people have four color eyes?

>>17082182
Wrong.

I think this is actually true.

Bruh brown eyes people developed most of the technology because they comprise the majority of humans on Earth, both now and in history

Anecdotally and N=1, I have blue-grey eyes and see really well in darkness.

>>17083089
Strange then that people with blue eyes live in parts of the world where we have to handle UV from high altitude, reflections from snow and/or water.
>>
>>17082153
if that was significant all Siberians and Inuit people would have selected the trait long ago. in fact, the trait would have become near-universal in Eurasian Homo Sapiens during the glaciation era. in reality, bright eyes are a very recent mutation, just a few millenia old. it stayed mostly confined to Northern Europe because it does create a weakness at lower latitudes, just like pale skin.
