How Do Polarized Sunglasses Work?
The useful glare-blocking properties of polarized sunglasses are well-known to just about anyone who goes outside. What isn't so well-known is how they reduce glare in the first place. That answer is deceptively complicated!

Specular Reflection
In this video Paul Andersen explains how light that is perfectly reflected creates specular reflection. The angle of the incident ray is equal to the angle of the reflected ray. Specular reflection is also known as mirror-like...

Refraction of Light
In this video Paul Andersen explains how light can be refracted, or bent, as it moves from one medium to another. The amount of refraction is determined by the angle of incidence and the index of refraction. Snell's Law can be used to...
