Best all around photochromic lens for all purpose use. Very clear to very dark and very dark back to clear very quickly. This is the basic Transitions and replaces Transitions VI as of January2014. It’s improvements are faster to dark and back to clear. And darker at temperatures over 85 degrees than Transitions VI. We recommend this version for most people.
Transitions X tra Active
This is the darkest of all Transitions versions because it has a starting tint of about 10%. Many folks may have a problem with the starting tint indoors in low light conditions and watching television.
This version is latest and greatest in Transitions technology. The optical world has waited a long time for this one. Vantage is similar to Transitions VII in that it is clear indoors but it not only darkens outdoors BUT POLARIZES TO ABOUT 50% OF A STANDARD POLARIZED SUNGLASS LENSE. This is the lens for folks that are rather stubborn and will not get that prescription sunglass like they should or for folks that want the very best performance in the their main pair of glasses. Like all Transitions versions U V radiation from the sun is necessary for activation. Therefore realize that the windshield of the car blocks a great deal of it that is needed to turn the lenses dark and why a pair if regular polarized sunglasses are necessary.
