THE DIAMOND HARD

Scratch protection system is an exclusive lens surfacing technology from Baush and Lomb that protects lenses from abrasion during outdoor sports or activities. An amorphous diamond surface coating make glass lenses 10x more scratch resistant than ordinary. it also reduces surface friction so water beads easily off the lens. The diamond hard surface is bonded permanently to the lens. it is available in the Ray Ban Survivors Collection.


RB- 50 ULTRA LENSES

Is photochromatic and adjust their density (darkness) according to light and temperature conditions. They darken most in cold, bright conditions which make them excellent for winter sports. These lenses also have exceptionally high (99.97%) polarizing efficiency. throughout their absorption range they block a greater percentage of blue light to improve contrast (80%-95% light absorption). Ultra lenses are fitted only to the Bravura model.


B 20 CHROMAX DRIVING LENS

Use Chromax Color Contrast Technology that increases the relative intensity and contrast of critical driving colors(reds, greens and amber). The use of neodymium, a rare earth element, selectively filters light from the driving environment to improve contrast and sharpen details. As a results, traffic signals, brake light and sign appear brighter and easier to see while glare is controlled. an advanced anti- reflective coating significantly cuts rear surface reflections from above and behind (80% light absorption). For example Ray ban use this chromax lens is Ray ban Chromax driving series.


GLASS POLARIZED LENSES

Have a polarizing filter to eliminate polarized reflections. These lenses enhance vision in high glare outdoor sports such as skiing, sailing and fishing. the neutral gray lens tint provides true color rendition and because they're made of glass, they offer superior scratch resistance (99.9% polarizing efficiency, 83% light absorption).



CHANGEABLE LENSES

Are available in gray and brown add adjust their depth of color for comfortable vision in any light. Like G15 gray natural vision lenses. changeable brown lenses provide accurate color perception (60%- 85% light absorption). Like B15 brown lenses, changeable brown lenses block haze-causing blue light to improve contrast and sharpen details (30%-80% light absorption)



AMBERMATIC LENSES

Are unique changeable lenses that adjust both color and density for changing weather/light conditions. They change from light amber/brown on overcast day to dark sunglass gray/brown under bright skies. they provide contrast enhancement under all conditions (25%-85% light absorption)

B-15 BROWN LENSES

Sharpen details while cutting glare for better vision under a variety of light conditions. these lenses filter out a large percentage of blue light to improve contrast and sharpen details (85% light absorption)

B-15 TOP GRADIENT MIRROR LENSES

Have all the features of the B-15 Brown Lenses, with the addition of a mirror across the top of the lenses, providing added protection from overhead glare, especially when one is driving (light absorption: 90% at top, 85% centre and bottom)



G- 15 LENSES

Are the most popular general- purpose Ray Ban lenses. with uniform absorption of colors throughout the spectrum, these lenses let colors be seen exactly as they are (85% light absorption). Is useful to avoid UV A/B 400 or 100% protection from sun which radiates ultraviolet causes eye diseases.



RB-3 GREEN LENSES

Have a light absorption curve that resembles the color sensitivity curve of the eye. maximum useful light reaches the eye for top visual acuity (75% light absorption).
