Product, Fit & Care

Every product page lists the frame measurements. Compare them with a pair you already own - most glasses have their measurements printed on the inside of the temple arm.

All our sunglasses have UV400 protection. Some models are polarized - the product page says which. Beyond that, each product page shows its options: lens colours, mirrored and non-mirrored tints, and Anti-Blue protection where available.

Studio photos are shot under controlled studio lighting, and lifestyle photos may be shot in the studio or outdoors. Tinted and mirrored lenses shift with the light around you - a stronger mirror effect in bright sun, subtler indoors. If your pair doesn't match what you expected, the Match Guarantee has you covered.

Use the included pouch or a microfiber cloth. A drop of lens spray or lukewarm water helps on smudges. Store them in their case, and keep them off the car dashboard - heat can warp frames.

Every order is covered by our two guarantees: Care (30 days - arrived damaged or defective, replaced free) and Match (7 days - not the right pair, 30% refund or a replacement, keep the glasses). Beyond that, if something seems wrong with your pair, email us - we stand behind what we make.

Yes - custom colour combinations are possible, for both regular and prescription pairs, and so are other custom requests (like transition lenses). Email us at info@on-slice.com with what you have in mind. Custom pairs are made to order at our production facility, so production and shipping are similar to prescription orders - see Prescription Glasses.
