Revant Replacement Lenses for Smith Sidney

Ever so slightly off

Lenses came protected in a lens pouch and in a solid box. Perfect condition. When I popped my old lneses out and put these ones in, one of the lenses is ever so slightly "loose" within the frame. I tried putting that lens in the other side of frame to see if that would work and it didn't, it's just that particular lens doesn't fit perfectly. When I clean them I can feel and hear the lens hitting the frame due to a tiny gap somewhere. Something only I would notice and it's not visible. It still looks great and is a high quality lens.
