I only wore these while driving, so there's almost no warping or damage. The current lenses correct my vision from 0.6 to 1.0 and also correct for astigmatism. You can bring these to OWNDAYS for a lens replacement and use them. The frame is made of titanium, so it's very light. These are the OM1004 model glasses. The case is new. - Brand: OWNDAYS - Model: OM1004 - Material: Titanium - Size: SDFT-139 Thank you for looking.
