Polarized lenses are used to reduce light reflections.
Advantages:
Polarized glasses allow true color perception.
Polarized glasses improve visual comfort, contrast and visual clarity. This reduces eye strain.
They are useful for cyclists, runners, guides and fishermen giving a clearer view by eliminating annoying reflections.
Polarized glasses also benefit water sports, stopping the glare and making the sea more transparent, where one can see fish and rocks beneath the surface of the water!
