Compatibility, Size and Fit
The frame is presented as a square model in a 51 mm size with 51 – 16 – 145 dimensions. That makes the size and shape the main checks before choosing an offer. The product also notes that the square model looks best on Oval-Round faces, which is a style guide rather than a guarantee of fit.
Before You Decide
Confirm the 51 mm size, the Transparent Light Brown colour and the non-polarised lens specification before you choose. If frame shape matters to you, keep the square style and the stated dimensions in mind as well.
