About the Synergy 6001
Synergy 6001 Prescription Glasses
Tortoiseshell is a classic, but it does not have to be brown. The Synergy 6001 takes the familiar mottled pattern and mixes in blue or purple, so you get the warmth of tortoiseshell with a bit more personality. It is a women’s full-rim plastic frame, sized 52-16-140, and it can be fitted with single vision, varifocal or bifocal lenses made to your prescription.
Havana/Blue or Havana/Purple?
Havana/Blue blends caramel tortoiseshell with denim and sky blue. It is fresh and easy to wear, and it looks great with blue or grey eyes, white shirts and casual outfits.
Havana/Purple mixes the same warm base with pink and violet. It is softer and more feminine, and it adds a lovely glow to fair and cool skin tones.
Shape and comfort
The shape is a soft rectangle that lifts slightly at the outer corners, which gives the face a gentle lift without being a full cat-eye. The plastic frame is light enough for all-day wear, and the full rim protects the lens edges from everyday knocks.
Who it suits
The gentle lift at the corners suits round and oval faces especially well, and the medium size works for most women. If you have always worn plain black or brown frames and want something a little more fun without going bold, the Synergy 6001 is a nice middle ground.
Size and fit
| Brand | Synergy |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Havana/Blue, Havana/Purple |
| Frame size | 52-16-140 mm (lens width, bridge, arm length) |
| Lens depth | 36 mm |
| Designed for | Women |
The 52mm lenses put the Synergy 6001 in the medium range, which suits most faces. The 16mm bridge is on the narrow side, so it sits nicely on slimmer noses, and the 140mm arms are a standard length. The 36mm lens depth works well with single vision and bifocal lenses, and with many varifocal designs too.
Lens options for the Synergy 6001
Choose the lens type that suits how you use your glasses:
- Varifocal lenses for clear vision at every distance without swapping pairs.
- Single vision for one job done well: driving, reading or desk work.
- Bifocal if you like a clearly marked reading section.
- Ready readers when you only need help close up.
If your prescription is on the stronger side, a thinner high-index lens keeps the edges neat, and an anti-reflective coating means fewer distracting reflections on screens and at night. You will also find this frame in our blue light glasses range.
Before you order
Check that your prescription is current; an eye test every couple of years is a good habit, and your optician will tell you how often you need one. You will also need your PD, which tells the lab where to centre the lenses so you look through the right spot. With those two things in hand, ordering takes just a few minutes: choose your colour, pick your lenses, enter your details and you are done.
From our lab to you
Every pair is made to order. Our UK optical lab cuts your lenses to your prescription, fits them into your Synergy 6001 and checks every pair before it leaves our lab.
Keep them looking new
Rinse off dust before wiping, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay straight. For more tips, see our lens care guide.
Questions we often get
What is havana?
Havana is another name for tortoiseshell: a mottled pattern of browns and ambers. On the Synergy 6001 it is mixed with blue or purple.
Is the Synergy 6001 comfortable for all-day wear?
Yes. It is a lightweight frame, and choosing a thinner lens for a stronger prescription keeps the overall weight down even further.
Will the Synergy 6001 suit a narrow nose?
Yes. The 16mm bridge is designed for slimmer nose bridges.
Can I get varifocal lenses?
Yes. The 36mm lens depth is enough for many varifocal lenses. If you are unsure, single vision and bifocal are always a safe choice.
Do you make the lenses yourselves?
Yes. Every pair is made to order in our UK optical lab, where your lenses are cut to your prescription and fitted into your frame.
