POLARIZED LENSES
 
    What are polarized lenses?
 
    Light enters the atmosphere from the sun being scattered. When this scattered light hits a reflective surface, it then becomes polarized and non-scattered. This non-scattered reflected light is “GLARE”. The reflected glare is blocked by the Linear Polarizer and does not enter the human eye.
    “GLARE” is highly intensive and is bothersome to eye and also causes visual discomfort and problems to see certain objects clearly. When we block the Glare with a polarizer, all we see is the visible light with comfort, allowing great detail in all objects that we see.
