Acetate over metal?
I got new frames recently, but the nose piece arms seem to move fairly easily, which throws my vision out of whack...and then I have to go get them adjusted again, which is a nightmare. Would acetate frames be better? Is this even normal? Could it be a problem with the lenses? Here's my Rx:
Right eye - 4.25 -4.25 x011
Left eye -6 -2.75 x170
