Question 331

Can you see out of sunglasses which shade both horizontally and vertically polarized light?
No. Such sunglasses would absorb all light and would appear black. Polarizing sunglasses are designed to absorb only horizontally polarized light; the light associated with glare. There is no reason to absorb vertically polarized light.
