Rendered Fits for eyewear and sunglasses
Frames are judged on how they look on a face and how they sit: bridge width, temple length and lens width against the face. Shoppers are unsure whether a shape will suit them and whether it will fit their head, and a flat product photo answers neither question.
Rendered Fits' size recommendation is built for garments and works from a size chart and fit notes, so it is not designed for frame measurements. For eyewear the relevant function is try-on imagery: a photo-based image of how a style looks on the shopper. It is a visual preview and does not establish physical fit. If you need live camera AR for frames, an eyewear-specialist tool may suit you better.
Nothing here is a guaranteed result. Measure it on your own store before rolling it out wider.
Install Rendered Fits from the Shopify App Store and choose which products show the “Try it on” button from the app dashboard. Size chart data matters for garments; for frames, keep your measurements (lens width, bridge, temple length) on the product page.
Start with a few frame shapes that shoppers often hesitate over, such as oversized and aviator styles, and compare appearance-related returns on those against similar frames. Try-on images are a visual preview and do not establish physical fit.

Try-on imagery applies: it shows how a style looks on the shopper's own photo. Rendered Fits' size recommendation is built for garments, so it is not a frame-fitting tool, and the image does not establish physical fit.
Not reliably. The size recommendation is built for garments, and support for other products depends on having usable size data. Keep lens width, bridge width and temple length on the product page.
No. Rendered Fits works from your existing product images, so no new shoot, 3D asset or developer is required.
