About the SMART
SMART Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The SMART is a unisex full-rim rectangular frame, sized 50-18-135, in Silver, Gold or Earth. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Rimless collection.
Choosing your SMART colour
Silver. Silver is a clean, bright silver. It is a quiet, professional finish that works with navy, charcoal and white.
Gold. Gold is a warm, soft gold. It is a warm, elegant choice that pairs nicely with earthy colours.
Earth. Earth keeps things simple. It is a versatile choice that works for most people.
Still torn? Think about what you wear on an ordinary weekday, not on a night out. That is the colour you will be happiest with.
Design details
Rectangular lenses suit round and oval faces, adding a bit of definition. With no rim around the lenses, the frame almost disappears on the face.
It is the kind of frame that works with most outfits, which makes the SMART an easy pick for everyday wear.
How to wear it
Keep the rest of your look simple and let the frame do the talking. It works just as well with workwear as it does with weekend clothes.
Frame size and fit
| Colours | Silver, Gold, Earth |
|---|---|
| Frame size | 50-18-135 mm (lens width, bridge, arm length) |
| Lens depth | 37 mm |
At 50mm per lens, it is on the smaller side, which is ideal if most frames feel too wide. The 18mm bridge is average. The 135mm arms are a standard length. Across the lenses and bridge it measures about 118mm.
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.
Lens options for the SMART
Choose the lens type that suits how you use your glasses:
- 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.
The 37mm lens depth works with single vision, bifocal and many varifocal lenses. 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
Your SMART 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.
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.
Your questions, answered
Can I get varifocal lenses in the SMART?
Yes. The 37mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the SMART as computer glasses?
Yes. Single vision lenses set to your screen distance, or varifocals if you also need distance vision, both work well for desk work.
Is it a small frame?
Yes. With 50mm lenses it suits smaller faces.
What does rimless mean?
There is no frame around the lenses. They are held by the bridge and arms only, which makes the glasses very light.
Where are my lenses made?
In our UK optical lab. They are cut to your prescription, fitted into your frame and checked before they are sent out.
