Better survival in cloudy N European conditions. Light colored eyes let in more light to see in darkness. Light skin and hair let more sunlight in for vitamin D production. Sunlight being more rare made these survival advantages.

If the above is true, why didn't it affect Eskimos, Lapps and indigenous Siberian peoples the same way.

Pre-industrial darkness was the same all over.

Because that's not how evolution works. Traits don't magically appear because they're logically advantageous.

Random mutations occur and it's up to chance whether they're useful or not. Most don't even make it out of the womb.

The Canadian tribes have light skin compared to the US tribes. If the gene for light eyes and hair had manifest in the mongoloid people, it would've been an advantage.

Africa and the mediterranian had more sunlight near the equator.

No it is not. It's dark for like 6 months out of the year when you go far enough north, I'm talking 24 hours a day

Apparently they started off Asian, and are on the way to lightening. They have the same eyelid fold as the Asians.

I'm pale skinned and green eyes. I work on rooftops in south Texas through the summer. I can handle it with sunscreen a hat and good sunglasses but then I watch these Mexicans come out on the roof and just bust ass in the heat and sun like it's nothing. Assholes, of course you never see old ones doing what I do, but you do see old white guys up here keeping up, not sure what to make of that.

Please start learning a skill so you don't have to be one of those old white people doing roofing in Texas summers.
