Color: 6-silver / Mirror | Lens Width: 60 Millimeters
arrived as replacement to broken stem, ooooold convertible-dedicated glasses judged "just right", maybe best of the lots, scattered around where needed.
Just right =
if they were any better and expensive (ala Ran-Ban Aviator) I would lose them within weeks, always have
if they were any worse, I would throw them away as visually irritating
That said, these are closer to Ran-Ban than throw aways or even those used for yardwork machines ("string" trimmers, et al.)

Thought the mirror version might be visually impairing ... trails thus far say NOT
Thought the price might bring cheap-don't-break-me glasses but they seem more sturdy than most
Thought the inability to try them on - as usual - in a store might bring me a poor fit .... NOT, fit very well

Arrived pretty fast, Mday shipping traffic concerning, so all a good experience.
