These are lightweight, titanium-framed glasses, the SAMURAI SHO SS-J207 #2 model. They have prescription, gradient lenses. (Visual acuity of approximately 0.3 to 0.1) No astigmatism. The gradient is subtle, a light touch. The color is gray. - Brand: SAMURAI SHO - Model Number: SS-J207 #2 58□15-140 - Material: Titanium - Made in Japan Retail Price: ¥41,800 Thank you for viewing. I purchased the frame new on the same site. Afterwards, I had the lenses put in at Megane Flower. I usually go without glasses, and only use them when driving. However, I often use a cheaper pair of glasses that I leave in the car, so I haven't used these glasses much, only a few times. When I'm not wearing them, I always kept them in their case, so they are in beautiful condition with no scratches. Also, I do not smoke. Although it may be difficult to see, the beetle mark, which is proof of authenticity, is clearly present. Among the Samurai Sho models, this is a relatively simple design, suitable for everyday use, such as for work. I apologize, but if the lenses do not match your prescription, please have them replaced at a nearby optician. The glasses will be wrapped in bubble wrap and shipped in a hard case to prevent shifting. Thank you for your consideration.
