Gripe of the morning: All eyeglass websites do faceting and search wrong.
Frame designs are fully segregated by "men" and "women". A minority have a "unisex" section. Sometimes it is an intersection of the gendered sets, sometimes it is an exclusive third set.
The only parameter I care to filter on is lens size. Very few accommodate that, and those that do require me to redo for each gender-section.
Eyeglass gender should be a category facet that can be toggled just like any other category.
@ardgedee I tend toward the men's frames when unisex is not an option because they suit my face and my personal style. The web sites follow the long established pattern of physical stores that have their inventory segregated into men/women/kids. Because kids need smaller frames due to face/head size, not because kids are ungendered.
@thatdawnperson @photopuck Nominal "women's" glasses often fit me better than "men's" because I have a narrow head combined with a large-ish Northern European's nose. "Women" and "men" are subjective rather than objective qualities, and should be a search parameter that behaves the same way as color and shape.
I became obsessive about glasses as my eyes got bad enough to limit the types of frames I could wear. I have very strong opinions about eyeglass frames, let me show you them... 👓
