About the Synergy 6055
Synergy 6055 Prescription Glasses
A rounded square gives you the softness of a round frame with a little more structure. The Synergy 6055 is a unisex full-rim plastic rounded square frame, sized 53-19-145, in Black/Brown or Blue/Brown. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Synergy range.
Black/Brown or Blue/Brown?
Black/Brown. Black/Brown mixes black and brown. It is the safest choice if you only want one pair, and it never looks out of place.
Blue/Brown. Blue/Brown pairs blue with brown. It warms up the face and sits nicely alongside camel, olive and cream.
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
The rounded corners and straight lines balance most face shapes, especially oval, square and heart-shaped faces. A soft colour fade defines the brow line and lets the lower half of the frame melt away.
Plastic keeps the weight down and allows richer, deeper colour than metal.
If you want a frame you can put on in the morning and forget about, the Synergy 6055 is a strong choice. The Synergy 6055 is an easy frame to wear every day.
Wearing it every day
It works with workwear and weekend clothes alike, which is exactly what you want from an everyday frame.
How it fits
| Brand | Synergy |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Black/Brown, Blue/Brown |
| Frame size | 53-19-145 mm (lens width, bridge, arm length) |
| Lens depth | 43 mm |
| Designed for | Men, Women |
The 53mm lenses make this a medium frame that suits most faces. The 19mm bridge is a little wider than average. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 125mm.
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 Synergy 6055
Your optician’s prescription will usually tell you which of these you need:
- 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 43mm, 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. Spend a lot of time on screens? This frame is also part of our blue light glasses range.
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 Synergy 6055 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
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 varifocal lenses in the Synergy 6055?
Yes. The 43mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the Synergy 6055 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 53-19-145: 53mm lens width, 19mm bridge and 145mm arms, a medium fit.
Is it unisex?
Yes. It suits men and women.
What does the colour fade look like?
The colour is darker at the top of the frame and becomes lighter towards the bottom.
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.
