Just this month we have Transitions Signature VII lenses became available on the market. What is the difference between older style Transitional lenses and the new Signature VII lenses? They become darker on hotter days, all suitable for all ages including children, faster transition (fade) speed, they are completely clear indoors and at night, and like all transitional lenses they still block 100% of damaging UV rays.
Transitions Signature VII lenses will work any prescription frame and most prescriptions out there.
