Review on ToughAsNails Men's Polarized Quarter Sunglass Replacement - The Ultimate Accessory by Aaron Jones

The shape is perfect and they fit perfectly in every way except depth/thickness and that is a critical flaw. With Quarter Jacket frames, the lenses are part of the design. Because these lenses are only 2/3 (maybe 3/4) the thickness of OEM lenses, they can flex and wobble a lot. These sunglasses no longer felt stable with framed lenses. If they were the same thickness as the OEM lenses they would be absolutely perfect and I couldn't say anything bad about them. However, they are not perfect and can cause the Quarter Jacket's frame to crack or fail with reduced structural strength.
