From a RayBan customer service employee:
The B15 is a brown lens and the G15 is a grey/green lens. Both lenses allow 15% light through the lens. It also blocks the UV reds and UVB rays.
From the bottom of a website( http://www.bardoptical.com/html/sunglasses.html ):
G-15 Lenses Historical Perspective In 1951, in response to a Navy Air Corps requirement, Bausch & Lomb began developing a truly neutral sunglass lens, called the N-15. This lens was reformulated slightly to make it more suitable for prescription use and renamed the G-15. The military services were so impressed that they wrote a complete set of specifications around the characteristics of the G-15 lenses. How the Lens Works Human eyes do not respond equally to all colors in the visual spectrum. The eyes are more sensitive to green and yellow wavelengths and are less sensitive to red and blue. Based on this knowledge, the G-15 lens was formulated to emphasize the colors that our eyes see most easily and de-emphasize less useful colors. The G-15 lens absorbs 85% of visibile light, transmitting only 15%. The light transmission curve of the G-15 (showing the amount of light that is allowed to pass through the lens) is similar to the color sensitivity of the human eye. What this means is that the lens transmits colors in the same way tha tour eyes are sensitive to colors. This results in natural vision - true colors that are easy on the eye. The G-15 lens is made of impact resistant optical quality glass. It provides 100% Ultraviolet (UV) protection, is naturally scratch resistant, and has outstanding stability with virtually no time-related fading or alteration of the tint.

What different lens types are on Ray Ban sunglasses?
# Polarized (reduce glare caused by light reflected from polarizing surfaces such as water.) # Non-Polarized# B15-XLT (Dark Brown) # G15-XLT (Dark Green) Some of the above can be plastic or glass. I'm not sure if the B15 & G15 XLT lenses are polarized; however, they do cost more money.
What is the difference between G-15 XLT and B-15 XLT lenses?
G-15 XLT lenses provide natural vision while maintaining true colors, offering better contrast. B-15 XLT lenses offer enhanced contrast and provide a warmer perception of colors compared to G-15 XLT lenses.
Are g15 xlt lenses polarized?
No. Polarized cost about $100 more.
How do g 15 xlt lenses compare to polarized lenses?
A polarized lens cuts more reflected glare but the actual protection of polarized lenses and G15 lenses are the same. Polarized sunglass lenses reduce glare reflected off roads, bodies of water, snow, and other horizontal surfaces where the G15 lenses do not.
What is a G-15 XLT sunglass lense?
The G-15 or G15 XLT is a Green-Gray lens that is the most popular general purpose lenses and used by a huge variety of sunglass makers. The 15 refers to the amount of light allowed to pass through the frame which in this case has approximately 85% light absorption. - Surfeyes.com
