These are navy titanium frame eyeglasses with prescription lenses. They were purchased at Kikuchi Megane, but I no longer use them because the prescription is no longer correct. My vision at the time of purchase was around 0.4 to 0.5, with only nearsightedness and no astigmatism. The frame is titanium, so it is strong against external forces. - Model name: Kenbunroku KE-8017 - Country of manufacture: PAN - Color: Navy - Frame material: Titanium - Lens type: Prescription Thank you for looking.
