GLASS POLARIZED LENSES
RA-52P (HIGH CONTRAST LENS) US PATENT No. 6773816 B2
RA-52P improved a contrast effect at being able to see clearly the three primary colors of light of the blue, green and the red and reduce the neutral color and was developed as the ultimate driving lens. There is an effect which shows a primary color effectively as the confirmation of the signal light of the blue, green and the red of the road sign, the confirmation of the brake lamp of the limber, and so on.
