Ray-Ban Chromax Sunglasses
Ray-Ban Chromax lenses incorporate patented Bausch & Lomb Color Contrast Technology which enhances the relative intensity and contrast of colors like red and green. As a result, brake lights, traffic signals and signs appear brighter and easier to see. Chromax lenses also filter out blue light haze to improve overall contrast and sharpen details, and they are scientifically formulated to control glare which can reduce eye fatigue. Chromax lenses are treated with an advanced anti-reflection coating that cuts down distracting reflections from the rear surface of the lenses. You'll find Chromax technology and Chromax lenses mostly in vintage Ray-Bans that are part of the Ray-Ban Driving Series. While never a guarantee of authenticity, all Bausch & Lomb Chromax lenses will have an etched lightning bolt following the laser etched Ray-Ban on the right lens.
Two of the best known Chromax lenses are the B&L Ray-Ban Ace (A-30) Chromax lens and G-20 Chromax lens. Both were made with the finest optical glasses specially formulated with Neodymium, a rare earth element to enhance the selected colors of the spectrum. The Ace A-30 Chromax lens was always popular with golfers among others, for when golfing the A-30 Chromax lens accentuates greens, blues, and reds. Contours on the course stand out better so it's easier to read greens and survey fairways. The Ace A-30 light tranmission of 30% is an ideal level for cutting glare while maintaining depth perception. The G-20 Chromax lens was designed for fast reaction sports such as tennis and emphasizes reds, greens, and ambers with a light tranmissance of 20%. The G-20 Chromax lens is exceptional for medium to strong glare. Both the Ace and G-20 Chromax lenses sharpen details and maintain excellent overall contrast for a wide variety of athletic endeavors and both are treated with an anti-reflective coating to minimize distracting reflections from the rear surfaces of the lenses.
Following the sale of the Ray-Ban brand to Luxottica in 1999, Bausch & Lomb ceased making Chromax lenses for Ray-Ban sunglasses and they ceased to be offered in the original form.
