Hakusan Megane Frameless Rimless Rimless Glasses Clear Yellow The structure uses not only the lenses and metal but also resin parts. It's interesting, like a cross between frameless and clear frame glasses. I bought these about 25-26 years ago and have kept them in storage. Perhaps as a reaction to thick-rimmed glasses, frameless glasses seem to be getting another look recently, so if you're looking for a pair, please consider these! The color is clear yellow from the beginning, not faded. However, there are some minor scratches, discoloration, and cloudiness. Please understand this. Prescription lenses are installed, so you may need to replace the lenses.
