About the Joia 3018
Joia 3018 Prescription Sunglasses
Good sunglasses keep the glare out. Prescription ones let you see the view as well. The Joia 3018 is a pair of women’s full-rim plastic cat-eye sunglasses, sized 54-17-135, in Havana. It can be made with your prescription, so you can see clearly and keep the sun out at the same time. It is part of our Joia collection.
The colour
Havana. Havana is a warm tortoiseshell. It is shown with brown lenses. It is a classic that looks relaxed and a little bit vintage.
Design details
The upswept outer corners suit round, oval and square faces especially well, giving the face a gentle lift. The plastic frame is light on the nose and comfortable for all-day wear.
Keep the Joia 3018 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
Pair them with a sundress and sandals for a beach day, or with a trench coat for a smart city look.
Size and fit
| Brand | Joia |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Havana |
| Frame size | 54-17-135 mm (lens width, bridge, arm length) |
| Lens depth | 46 mm |
| Designed for | Women |
The 54mm lenses put it at the upper end of medium. The 17mm bridge is average. The 135mm arms are a standard length. Across the lenses and bridge it measures about 125mm.
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 Joia 3018
The Joia 3018 can be made with any of these lens types:
- Varifocals if you want to see near and far without swapping glasses.
- Single vision for one task done well, such as driving, reading or screen work.
- Bifocals if you prefer a clearly defined reading area.
- Ready readers for straightforward close-up help.
At 46mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. Want lighter lenses? A high-index lens is thinner than standard plastic. Pair it with an anti-reflective coating for less glare when you drive after dark.
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
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Joia 3018 and checked by our technicians before they are sent 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.
