About the Solo 618
Solo 618 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The Solo 618 is a unisex full-rim rectangular frame, sized 51-16-135, in Blue. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Solo collection.
About the Solo 618 colour
Blue. Blue is a clear, easy-to-wear blue. It looks great with blue or grey eyes and pairs easily with denim and white.
Design details
Rectangular lenses suit round and oval faces, adding a bit of definition. A crystal front looks modern and light, and it goes with everything.
Whether it is your main pair or a spare, the Solo 618 is easy to live with.
Wearing it every day
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
| Brand | Solo |
|---|---|
| Colours | Blue |
| Frame size | 51-16-135 mm (lens width, bridge, arm length) |
| Lens depth | 32 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 16mm bridge is on the narrow side. The 135mm arms are a standard length. Across the lenses and bridge it measures about 118mm.
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.
Lens options for the Solo 618
Pick the lenses that match your prescription:
- 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 32mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. 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.
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.
How your glasses are made
Your Solo 618 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
Rinse off any grit before you wipe, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay aligned. See our lens care guide for more.
Questions we often get
Is the Solo 618 suitable for varifocals?
The 32mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Can I wear the Solo 618 for driving?
Yes. Single vision lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 51-16-135: 51mm lens width, 16mm bridge and 135mm arms, a medium fit.
Will it suit a narrow nose?
Yes. The 16mm bridge is designed for slimmer noses.
What does crystal mean?
A clear, see-through finish.
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.
