Q: What does the size 56 × 18 × 140 mean?
A: The measurements are in millimetres: 56 mm is the width of one lens, 18 mm is the bridge width between the lenses, and 140 mm is the length of each temple arm. Compare them with a pair you already find comfortable to help judge the fit.

Q: Will these sunglasses fit me?
A: The measurements provide a useful starting point, but fit also depends on your face shape and how the bridge sits on your nose. Comparing the 56 × 18 × 140 mm size with your current sunglasses is the best way to assess it before ordering.

Q: What colour are they?
A: The product colour is listed as black. Please refer to the photographs for the appearance of this particular pair.

Q: What condition are the sunglasses in?
A: They are listed in very good condition, with light traces of use on the exterior and interior. The hardware is shiny with light scratches. As these are pre-owned sunglasses, please review the photographs for a closer look at their condition.

Q: Do they come with a case?
A: Yes. A case and a dust bag are included, as listed in the product information.

Q: Are the lenses polarised, and what UV protection do they provide?
A: Polarisation and UV-protection specifications have not been provided for this pair, so neither can be confirmed from the listing. They are separate properties; if you need a particular level of sun protection, ask an optician to check the lenses before relying on them outdoors.

Q: Can I have prescription lenses fitted?
A: Lens replacement has not been confirmed for this frame. An optician can inspect the sunglasses and advise whether suitable prescription lenses can be fitted without damaging them.

Q: How should I clean and store them?
A: Gently clean the lenses and frame with a damp cloth and a mild, neutral detergent, then dry with a soft, clean cloth. Avoid solvents and harsh cleaners. Store the sunglasses in their case when not in use, and do not leave them in a hot car or in prolonged direct sunlight.

Q: How do I know they are authentic?
A: A Retro Tale states that its pre-owned items are checked by its experts and guarantees their authenticity. The included case and dust bag are listed in the product information; an authenticity card is not listed as included.
