About the Synergy 6044
Synergy 6044 Prescription Glasses
A good square frame is the white T-shirt of eyewear: simple, reliable and always in style. The Synergy 6044 is a women’s full-rim plastic square frame, sized 52-15-140, in Brown Havana or Red Havana. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Synergy range.
Choosing your Synergy 6044 colour
Brown Havana. In Brown Havana, the frame is brown tortoiseshell. It flatters warm and olive skin and works with almost any outfit.
Red Havana. The Red Havana version is red tortoiseshell. 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.
The details
Square lenses add structure to round and oval faces and make features look more defined. Plastic keeps the weight down and allows richer, deeper colour than metal.
It is the kind of frame that works with most outfits, which makes the Synergy 6044 an easy pick for everyday wear.
Wearing it every day
For work, pair it with a crisp shirt or blazer. At the weekend it looks just as good with a T-shirt and jeans.
How it fits
| Brand | Synergy |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Brown Havana, Red Havana |
| Frame size | 52-15-140 mm (lens width, bridge, arm length) |
| Lens depth | 37 mm |
| Designed for | Women |
The 52mm lenses make this a medium frame that suits most faces. The 15mm bridge is narrow, so it sits securely on a slimmer nose. The 140mm arms are a standard length. Across the lenses and bridge it measures about 119mm.
To check the fit, look at the three numbers printed inside the arm of glasses you already own. If they are within two or three millimetres, this frame should feel similar.
Lens options for the Synergy 6044
Pick the lenses that match your prescription:
- 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.
The 37mm lens depth works with single vision, bifocal and many varifocal lenses. 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.
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 Synergy 6044 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.
FAQs
Can I get varifocal lenses in the Synergy 6044?
Yes. The 37mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the Synergy 6044 comfortable for all-day wear?
Yes. It is a lightweight frame, and a thinner lens for a stronger prescription keeps the weight down even further.
What size is it?
It is size 52-15-140: 52mm lens width, 15mm bridge and 140mm arms, a medium fit.
Will it suit a narrow nose?
Yes. The 15mm bridge is designed for slimmer noses.
What is havana or tortoiseshell?
A mottled pattern of browns and ambers, a classic eyewear 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.
