## 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.

| Frame or guide label | Lens · bridge · temple | How to read it |
| --- | --- | --- |
| Greer Black/Grey Polarized · Medium | 50–23–145 mm | 50 mm lens width, 23 mm bridge width, 145 mm temple length. |
| Greer Tawny Tortoise/Brown · Medium | 50–23–145 mm | The same three dimensions appear on a separate color and lens listing. |
| DIFF fit guide · women’s sunglasses | 40–62 mm lens-width range | Broad shopping guidance; use the measurements on the selected frame for a model-level comparison. |

## 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.

| DIFF listing | Selected finish and lens | Record identity |
| --- | --- | --- |
| Greer Black/Grey Polarized | Black frame; grey polarized lenses | https://www.diffeyewear.com/products/greer-black-grey-polarized-sunglasses |
| Greer Tawny Tortoise/Brown | Tawny tortoise frame; brown non-polarized lenses | https://www.diffeyewear.com/products/greer-tawny-tortoise-brown-sunglasses |

## 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.

| Product-page field | Greer page wording reviewed | Catalog treatment |
| --- | --- | --- |
| UV statement | 100% UVA/UVB protection | Retain the retailer’s stated rating and exact product association; do not infer additional health or performance claims. |
| Lens material | Premium scratch-resistant polymer | Keep the material and scratch-resistant wording as the page states it. |
| Frame material | Hand-cut acetate | Attach to the Greer model page rather than assuming the material applies to every DIFF frame. |
| Polarization | Shown for Black/Grey; not shown as polarized for Tawny Tortoise/Brown | Record the selected lens option’s status; do not infer it from the model name alone. |

## 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.

| Catalog type | Useful visible fields | Boundary |
| --- | --- | --- |
| Sunglasses | Frame, color, lens tint, polarization when stated, dimensions | Use the chosen color and lens combination from the product page. |
| Optical or prescription frame | Frame measurements and prescription-lens availability as presented | Do not store a customer’s personal prescription values in a public product catalog. |
| Readers | Product type and displayed reading-strength options | Capture only strengths the selected listing actually offers. |
| Blue-light glasses | Product type, frame option and lens attributes shown | Do not infer suitability or effects beyond DIFF’s own product wording. |

## Compare offers and policies at the item level

The policy wording below was recorded from official DIFF product results checked October 4, 2026. Direct product-page opens did not expose their detail bodies; the item-specific sale state is a dated indexed listing observation, not an assumed checkout state. Confirm the selected option and posted terms before relying on it. No price amount is reported here.

| Field or state | DIFF page observation | Preserve separately |
| --- | --- | --- |
| Price and promotion | Capture only the amount and promotion shown for the selected option at observation time, with currency, exact URL and timestamp. | Record the displayed regular and sale prices, currency, discount label, selected option, exact URL and observation time together. |
| Final sale | The official Greer Kombu/Grey result reviewed October 4 is marked “Final sale item”; DIFF’s product-page policy says sale items are final sale and not eligible for returns or exchanges. | Attach the dated status to the Greer Kombu/Grey listing and its exact option; do not copy it to other Greer colors or products. |
| Non-prescription return | Current DIFF product results state non-prescription returns within 30 days of purchase for an exchange or refund, subject to the sale exception. | Keep the item type and the policy page or listing evidence with the return window. |
| Prescription exchange | Current DIFF product results state prescription items may be returned within 14 days of delivery for exchange; keep the delivery-based clock distinct from the non-prescription window. | Keep the delivery-based clock distinct from the non-prescription return period. |
| Warranty and protection | Greer product pages show a one-year warranty badge. The separate Worry-Free Protection Plan page offers two-year plans for one pair or two pairs, purchasable up to 14 days after the original order; theft and loss are excluded. | Record the included badge and optional plan separately from the frame price, exact listing and included accessories. |
| Collaboration and included items | A collaboration or offer label alone does not establish discount eligibility. The selected product page must name any included case, cloth, lens upgrade or protection plan. | Keep collaboration attribution, promotion exclusions, included accessories and optional add-ons attached to the exact listing. |

## Use current giving copy and site-use terms with their dates

The DIFF Gives Back page reviewed October 4, 2026 names Vision to Learn and describes school-based screenings, mobile-clinic exams and glasses delivery; it says the partnership focuses on schools where at least 50% of students qualify for Free and Reduced Lunch. DIFF says purchases help support the work but does not state a fixed pair-for-pair donation rate. Its Terms of Use show a June 11, 2026 update date; Sections 3 and 15 set the separately attributed access and content-use boundaries below.

| Source context | Published wording or review status | How to represent it |
| --- | --- | --- |
| Vision to Learn | Current DIFF Gives Back page names Vision to Learn, describes screenings, exams and glasses delivery at schools, and says purchases help support the partnership; its stated focus is schools where 50% or more of students qualify for Free and Reduced Lunch. | Attribute the statement to DIFF; do not turn it into a fixed donation count or rate. |
| Automated access · §§3 and 15 | The Terms of Use prohibit bots, scrapers, crawlers or similar automated tools without prior written permission. | Treat public page visibility as distinct from permission; link the dated Terms before planning automated access. |
| Copying and reuse · §15 | Section 15 separately restricts copying, scraping, AI-model training and other exploitation of site content without permission. | Obtain applicable permission before copying or reusing DIFF site content. |
