Question

An angler experiences a glare of light coming from the water's surface. Which type of glasses should she wear to minimize the glare?

Answer 1

The glasses that she should wear are the glasses that block horizontally polarized light coming from glares, like polaroid sunglasses, because these type of glasses block out the light being reflected from the water's surface by the vertically oriented polarizers in the lenses. 

Answer 2

Explanation :

An angler experiences a glare of light coming from the water's surface. Polarized glasses are used to minimize the glare coming from water.

When light is reflected from flat surfaces, it has the ability to move in a multi-direction. The reflected light has a very high intensity which can cause glare and can decreases visibility.

By using polarized sunglasses, the glare can reflect off to the ground, water bodies etc.
