The meaning of the 'P' on many Ray-Ban sunglass lenses may be confusing at first sight. It is usually found in the corner of a lens in white writing.
WHEN YOU BUY A PAIR OF RAY-BAN SUNGLASSES, WHAT DOES THE P ON THE LENS STAND FOR?
The P on the Ray-Ban lens stands for just that: polarized. It’s a way for customers to distinguish which lenses are polarized and which are not. Many sunglasses in Ray-Ban's assortment are sold in both polarized and non-polarized versions. In order to distinguish between the two, Ray-Ban has added a ‘P’ on the lens of the polarized ones.
This P is located on the left lens. It is usually in white screen print adjacent to the Ray-Ban logo.

WHAT ARE POLARIZED LENSES?
Many customers will buy a pair of Ray-Ban sunglasses without knowing they are polarized. There are those that will only buy polarized lens sunglasses, and others who particularly don’t care or who don't know what polarized lenses do.
Polarized lenses are transparent material on a lens. The lens could be glass or plastic. Either way, polarized lenses block certain types of light waves. This is really to block as much glare as possible from hitting your eyes. If you play sports, go fishing, or are frequently driving in the sun, then you’re best suited to purchase a pair of polarized sunglasses.
