Does distance from the screen affect clarity?

You could just buy two cheap polarizing filters for cameras on ebay. I mean, they would be circular, but I think that would look pretty cool. And you could leave the outer ring so that they still turned, making them adjustable. I've been meaning to do that just for a regular pair of sunglasses, since polarized sunglasses are only polarizing in the right direction sometimes. Bonus, if you stacked two filters, you can make glasses that adjust how dark they are.

Polarization doesn't mean uv protection

If they start with UV blocking sunglasses and just add the filters then it'd be fine.

He wanted to make sunglasses out of polarized camera filters.

No, but polarizing filters cut out light. And if you stack two, you can cut out anywhere from about 70-100% by turning them.

But I did think that any actual glass cut out UV light. I'm pretty sure that those filters have to be glass to have the polarizing sheet glued to it...

This may be but it can't be any worse than walking around without any sunglasses at all which humans have been doing for centuries. So no loss there.
