About the Retro Collection Retro Sun 020
Retro Sun 020 Prescription Sunglasses
Round glasses have a quiet, clever charm that never really goes out of style. The Retro Sun 020 is a pair of unisex full-rim stainless steel round sunglasses, sized 49-21-140, in Gold or Silver. It can be made with your prescription, so you can see clearly and keep the sun out at the same time. It belongs to the Retro Collection.
Gold or Silver: which one is you?
Gold. Gold is a warm, soft gold. It is shown with gradient lenses. It suits warm and olive skin tones beautifully.
Silver. Silver is a clean, bright silver. It is shown with grey lenses. It is a quiet, professional finish that works with navy, charcoal and white.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
About the Retro Sun 020 design
Round frames soften angular features, so they are a great match for square and heart-shaped faces. Stainless steel is strong, light and resistant to corrosion, so the frame keeps its finish over time.
Keep the Retro Sun 020 in the car, take it to the beach or wear it on your lunch break; it is ready for bright summer days.
Wearing it every day
Keep a pair in the car and another in your bag and you will never squint at the glare again.
Size and fit
| Brand | Retro Collection |
|---|---|
| Frame | Full Rim, Stainless Steel |
| Colours | Gold, Silver |
| Frame size | 49-21-140 mm (lens width, bridge, arm length) |
| Lens depth | 42 mm |
| Effective diameter | 49 mm |
With 49mm lenses, this is a compact frame that suits smaller faces. The 21mm bridge is wider than average, which suits a broader nose bridge. The 140mm arms are a standard length. Across the lenses and bridge it measures about 119mm.
Not sure about sizing? Compare these numbers with the ones on the inside arm of a pair that fits you well. A difference of two or three millimetres or less usually means a similar fit.
Prescription lenses for the Retro Sun 020
The Retro Sun 020 can be made with any of these lens types:
- Single vision: one prescription across the whole lens, for distance, reading or the computer.
- Varifocal: near, intermediate and distance in one lens, with no visible line.
- Bifocal: a separate reading segment in the lower part of the lens.
- Ready readers: simple magnification if you just need help with close work.
At 42mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. If your prescription is high, a high-index lens keeps things thin. An anti-reflective, scratch-resistant coating is a sensible extra for everyday wear.
Ordering online is simple
You need a valid prescription from your optician and your pupillary distance (PD), the distance between your pupils. Many opticians include your PD on the prescription; if yours does not, just ask for it. Choose your colour, pick your lens type, enter your details and add any lens upgrades. If you are unsure about size, compare the measurements above with a pair you already wear.
Made for you in our UK lab
Your Retro Sun 020 is glazed in our UK-based lab. Once you have chosen your lenses and entered your prescription, we cut and fit the lenses and check the finished glasses before they go out.
A little care goes a long way
Use lens spray and a soft cloth, fold the arms before putting your glasses down, and store them in a hard case. Our guide to looking after your lenses covers the rest.
FAQs
Can I get the Retro Sun 020 with my prescription?
