Question: What are Polaroid Sunglasses & How they Reduce Glare ?
The light waves which vibrates in a single plane are called polarized light . “ To bring the vibration of light in a particular direction is called polarization ” .
Polaroid filter is used to polarizes light due to the chemical composition of filter material . All the molecules of filter are oriented in same direction so they absorb light of same polarization .
Polarized sunglasses blocks the horizontally polarized light and allowing the vertical waves . As light waves travels only in one direction through polarized lenses , hence glare is reduced .
