About the Joia 3023
Joia 3023 Prescription Sunglasses
Good sunglasses keep the glare out. Prescription ones let you see the view as well. The Joia 3023 is a pair of women’s full-rim plastic square sunglasses, sized 55-17-135, in Purple. It can be made with your prescription, so you can see clearly and keep the sun out at the same time. You will find it in our Joia range.
The colour
Purple. The Purple version is patterned purple. It is shown with grey lenses. It works beautifully with navy, grey and silver jewellery.
The details
Square lenses add structure to round and oval faces and make features look more defined. The patterned finish means no two angles look quite the same.
The plastic frame is light on the nose and comfortable for all-day wear.
Keep the Joia 3023 in the car, take it to the beach or wear it on your lunch break; it is ready for bright summer days.
Styling tips
Big earrings and a bold lip make these sunglasses feel even more glamorous.
Frame size and fit
| Brand | Joia |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Purple |
| Frame size | 55-17-135 mm (lens width, bridge, arm length) |
| Lens depth | 45 mm |
| Designed for | Women |
With 55mm lenses, this is a larger frame that suits wider faces. The 17mm bridge is average. The 135mm arms are a standard length. Across the lenses and bridge it measures about 127mm.
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 3023
The Joia 3023 can be made with any of these lens types:
- Single vision: the same prescription from edge to edge.
- Bifocal: distance at the top and a reading segment at the bottom.
- Varifocal: a smooth change from distance to reading, with no line.
- Ready readers: a fixed magnification for books, phones and screens.
At 45mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. With a stronger prescription, a thinner high-index lens keeps the edges slim, and an anti-reflective coating cuts reflections from screens and street lights.
Before you order
Make sure your prescription is in date; most adults in the UK are advised to have an eye test every two years, and your optician will tell you if you need one sooner. You will also need your PD, which tells our lab where to centre the lenses. With those two things ready, ordering takes a few minutes: choose your colour, pick your lenses, enter your details and you are done.
From our lab to you
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Joia 3023 and checked by our technicians before they are sent out.
Keep them looking new
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.
Questions we often get
Can I get the Joia 3023 with my prescription?
Yes. Choose single vision, varifocal, bifocal or ready reader lenses when you order.
Can I get varifocal lenses in the Joia 3023?
Yes. The 45mm lens depth gives varifocal lenses enough height for all three vision zones.
Is it a large frame?
Yes. With 55mm lenses it suits wider faces.
Who glazes my lenses?
Our own optical lab in the UK. Your lenses are made to your prescription and fitted into the frame before your glasses are sent to you.
