Answer 2

Explanation:

1. Polarized glasses can block some of the reflected light, reducing dangerous glare and making driving safer. However, polarized sunglasses will have little effect when the sun is in certain positions in the sky. Motorcycle riders should avoid polarized glasses.
2. Polaroid sunglasses use long chain molecules in a coating on the lenses. ...
3. Sunglasses are useful for cutting out glare. The glare is due to light reflected from the horizontal surface, which is mostly horizontally polarised. Glare from water or shiny horizontal surfaces is effectively reduced by good sunglasses.
