What Type Of Lens Is Rayban Using On Their Sunglasses
Ray-Ban uses four different types of lenses for their sunglasses. The B15 XLT lens, the G15 XLT lens, polarized lenses and normal lenses, which we won’t discuss here because there’s nothing special about them (they just come in different colors).
B15 XLT Lens Ray-Ban B15 XLT lenses are brownish in color, block 100% of all UV rays and allow only 15% of the visible light to pass through them (that’s an 85% reduction!). These brown lenses also offer a bit more contrast by cutting down on the amount of blue light, as opposed to a G15 lens (which is described in the next paragraph). Blue light is very easily captured by the eye and has the effect of softening other colors that are harsher to our vision. In other words, by reducing the amount of blue light, the differences between colors and brightness of objects are more pronounced.
