DIFF Eyewear product data: frame measurements and lens options

Compare DIFF frames by fit measurements, color, lens, polarization, UV and prescription options. Date prices, promotions and returns to the exact listing.

Frame measurements are model-level fit evidence

DIFF presents frame measurements in lens width, bridge width and temple length order. Its Greer listings show 50–23–145 mm and use the size label Medium. Treat that label as DIFF’s broad lens-size category, then compare the millimeter values with a frame that fits; measurements do not guarantee fit.

Lens configuration changes the listing

The two Greer pages keep the frame name and 50–23–145 mm measurements while changing the selected color, lens tint and polarization. Keep each exact product URL and selected option as the listing identity; if a price or promotion is visible, capture it for that exact option with an observation time instead of carrying it across variants.

Keep optical claims attached to their product

Preserve the values DIFF publishes for the selected product and lens option. Attribute retailer statements to DIFF; a catalog field is not an independent certification or a medical conclusion.

Separate sunglasses, optical frames, readers and prescription options

DIFF’s catalog includes sunglasses, optical and prescription frames, readers, blue-light glasses, accessories and collaborations. Model product type and the options shown on that listing separately so one category’s fields do not get applied to another.
