"My prescription is fairly mild (-2 and -4). I've asked my trusted optician about this over the years, but he really doesn't want to do it."
Well, your optician knows your eyes better than you since you have a history of care with him now
you "trust" him but don't want to listen to his sound advice. What the hell is that?
The easiest, cheapest, and far and away the best is optician recommended fit over glasses
that will protest your eyes from any incoming road debris and sunlight. This brand is
what my doctor gave me and I wouldn't trade'm for anything they work so well.

You CAN see better than you might think with these fit overs. Oh yes, this advice will work for you
unless you are a fashion slave that needs to look "cool".
