Prada Sunglasses

Q: What do the numbers 55-19-140 mean on these Prada sunglasses?
A: They are the frame measurements in millimetres: 55 is the lens width, 19 is the bridge width (the part over your nose), and 140 is the temple (arm) length. If your current frames are close to these numbers, the fit should feel similar.

Q: Will this oversized geometric shape suit me?
A: With a 55 mm lens width and a 19 mm bridge, this style generally suits medium to wider face widths and offers a bold, fashion-forward look. The geometric silhouette adds coverage and works well for most face shapes that like an oversized fit.

Q: Do the brown gradient lenses provide UV protection?
A: Modern Prada sun lenses are designed to block harmful UV rays. Gradient lenses typically still provide full UV protection even though the tint fades towards the bottom. As this is a vintage pair, if you need confirmation for this exact item, we can check UV protection with a tester on request.

Q: Are the lenses polarised?
A: This pair is described as having brown gradient lenses and is not marked as polarised. If polarisation is essential for reducing glare (for example near water or on snow), an optician can usually fit polarised prescription or non‑prescription replacement lenses to acetate frames.

Q: Can an optician fit prescription lenses into this frame?
A: Yes, most acetate frames like this can accept prescription sun or clear lenses. Share the frame size 55-19-140 with your optician, and note that vintage acetate may require careful handling and heat-adjustment by a professional.

Q: Are the nose pads adjustable?
A: These have an acetate bridge without separate metal nose pads, so on-the-spot adjustment is limited. However, an optician can make gentle heat adjustments to the bridge and temples for a more tailored fit.

Q: What is included with this item?
A: Everything included is listed under the product information on this page. For this specific pair, a case is included as shown in the product information and images.

Q: What is the condition of this vintage pair?
A: Very Good. You may see light traces of use on the frame and shiny hardware with light scratches, consistent with careful wear. Please review the photos for close-ups of condition details.

Q: How should I care for tortoiseshell acetate frames and lenses?
A: Rinse with lukewarm water and a drop of mild soap, then dry with a clean microfibre cloth. Avoid solvents (acetone, alcohol), avoid leaving them in high heat (like a hot car), and store them in the case when not in use to prevent warping or scratches.

Q: How do you authenticate Prada eyewear?
A: Every piece at A Retro Tale is examined by our specialists using multi‑point checks of materials, construction, logos and temple codes, hinge quality, and country-of-origin markings. We stand behind the authenticity of all items we sell and can share additional photos or details on request.
