Different types of Lenses Employed by Ray-Ban

Ray-Ban utilizes 4 differing kinds of lenses for their sunglasses. The B15 XLT lens, the G15 XLT lens, polarized lenses and ordinary lenses, which we cannot focus on listed here for the reason that there's nothing Particular about them (they just appear in various colours).

B15 XLT Lens

Ray-Ban B15 XLT lenses are brownish in colour, block 100% of all UV rays and permit only 15% on the seen light to go through them (that's an 85% reduction!). These brown lenses also give a little bit more contrast by slicing down on the level of blue gentle, versus a G15 lens (that is described in another paragraph). Blue gentle is extremely quickly captured by the eye and has the effect of softening other colors which have been harsher to our eyesight.

That is why drivers have issue looking at the street ahead of these when they're driving in really sunny ailments (If your Sunlight is ahead of them).

Polarized lenses have a laminated surface with vertical stripes that develop a filter, which efficiently cuts out the horizontally-polarized light and lets only vertically-polarized light-weight in. Basically, should you occur being on a clear lake you could most likely see beneath the surface or should you be driving, Now you can begin to see the highway forward.
