Transitions VII Eyeglass Lenses
Transitions VII is the best all-around photochromic lens for all-purpose use.
They convert from very clear to very dark back and back to very clear quickly.
These lenses are the basic Transitions and replace Transitions VI as of January 2014. Its 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.
