I purchased glasses from ZOZOTOWN that came with a lens replacement voucher, and then had the lenses replaced with blue light 33% cut lenses at a Zoff store. These are non-prescription, fashion glasses. Although they were categorized as women's, the size is suitable for men as well. I've only used them a few times. There is no warranty. They come with a Zoff case (I don't remember if it was the case for this specific model...). ZOZOTOWN Information: Retail Price: ¥9900 Temple: 14.2 Frame: 3.7 x 14.3 Lens: 3.7 x 5.2 The lens replacement voucher is a ticket that allows you to exchange the lenses for "set lenses" once at a store. *Set lenses are single-focus lenses with a refractive index of 1.55, spherical design, and UV380 protection. Both prescription and non-prescription glasses can be made.
