These black Dita Eyewear Altrist round optical glasses are crafted in Japan. Boasting rounded acetate rims, they feature adjustable nose pads, a gold tone titanium bridge inlay, sculpted hinge piece, ultra-thin gold tone titanium temples with pressed line detail and curved tips. They are presented in a protective black carry case. These Dita Eyewear glasses are designed from the point of view of an engineer, and we must say, they certainly have an eye for detail. These glasses are sublime.
