I will be most grateful if someone can advise me regarding which frame
style is easier for a layman to change the lenses. I'm guessing the
full frames with the retainer screw would be the easiest, but, I could
be wrong. The frames and lenses will be identical (except for the
prescription, of course). I will be getting the glasses from an online
supplier, so there is no chance of the supplier doing it for me.
