About the Solo W39
W39 Prescription Sunglasses
If you wear glasses, prescription sunglasses are the easiest upgrade you can make. The W39 is a pair of unisex full-rim square sunglasses, sized 51-20-145, in Matt Black or Matt 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 Solo range.
Matt Black or Matt Havana: which one is you?
Matt Black. Matt Black is a soft, non-shiny black. It is shown with grey lenses. It looks sharp at work and just as good with jeans at the weekend.
Matt Havana. The Matt Havana version is tortoiseshell. It is shown with brown lenses. It is a classic that looks relaxed and a little bit vintage.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
The details
Square lenses add structure to round and oval faces and make features look more defined.
Keep the W39 in the car, take it to the beach or wear it on your lunch break; it is ready for bright summer days.
Styling tips
Keep a pair in the car and another in your bag and you will never squint at the glare again.
Frame size and fit
| Brand | Solo |
|---|---|
| Colours | Matt Black, Matt Havana |
| Frame size | 51-20-145 mm (lens width, bridge, arm length) |
| Lens depth | 41 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 20mm bridge is wider than average, which suits a broader nose bridge. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 122mm.
The easiest way to check is against glasses you already love. Most frames show their size inside the arm; if yours are close to these, you are in safe territory.
Prescription lenses for the W39
The W39 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 41mm, 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.
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 W39 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.
Looking after them
Clean your lenses with a microfibre cloth rather than your jumper, keep them in their case when they are in your bag, and do not leave them on a sunny car dashboard. Our lens care guide has more tips.
FAQs
Can I get the W39 with my prescription?
Yes. Choose single vision, varifocal, bifocal or ready reader lenses when you order.
Can I get varifocal lenses in the W39?
Yes. The 41mm lens depth gives varifocal lenses enough height for all three vision zones.
What size is it?
It is size 51-20-145: 51mm lens width, 20mm bridge and 145mm arms, a medium fit.
Will it suit a wider nose bridge?
Yes. The 20mm bridge is wider than most frames.
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.
