B&L Ray-Ban Changeables Sunglasses

B&L Ray-Ban Changeables sunglasses incorporate unique B&L photochromatic lenses that react to the sun's brightness to protect your eyes in all light conditions. Regular Ray-Ban Changeables sunglasses darken to compensate for varying outdoor light conditions. Ray-Ban Super Changeables darken even more for stronger light conditions and more sensitive eyes, and both Changeables and Super Changeables filter out 100% of harmful UV rays that can harm your eyes. This change in lens density which results in the lightening and darkening is a lifetime feature of these B&L Ray-Ban lenses and will not disappear or weaken over time.

 

Ray-Ban Changeables sunglasses darken to 75% of their full capacity within the first minute of exposure to sunlight. Out of sunlight, they lighten half way within the first 10 minutes and about 75% within the first 90 minutes. When new, Ray-Ban Changeables sunglasses and lenses require a breaking in period of several complete darkening / lightening cycles to bring them up to their normal performance. Changeables lenses were also heat treated to make them very impact resistant, but they are not shatterproof or breakproof nor do they have the extreme scratch protection characteristic of Ray-Ban Diamond Hard lenses. B&L Ray-Ban Changeable photochromatic lenses were made to the same standards of optical excellence for which B&L was always known. Following the sale of the Ray-Ban brand to Luxottica in 1999, Bausch & Lomb ceased making Changeables lenses for Ray-Ban sunglasses and they ceased to be offered in the original form.
