About the Synergy 6042
Synergy 6042 Prescription Glasses
If you want a frame with a bit of attitude, start with a cat-eye. The Synergy 6042 is a unisex full-rim plastic cat-eye frame, sized 52-20-145, in Black or Blue. You can order it with single vision, progressive or bifocal lenses made to your prescription. You will find it in our Synergy collection.
Black or Blue?
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Blue. In Blue, the frame is translucent blue. It reads as smart and dark from a distance, with a little more personality up close.
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
The upswept outer corners suit round, oval and square faces especially well, giving the face a gentle lift. Because the colour is see-through, the frame has a light, glowing look.
Small metal studs at the corners add a neat, vintage finishing touch. 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 6042 is a strong choice. For a frame you will reach for daily, the Synergy 6042 is a solid choice.
Wearing it every day
Because it is unisex, it is easy to share the look across the household. Pick the colour that matches your wardrobe rather than worrying about who it is designed for.
Size and fit
| Brand | Synergy |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Black, Blue |
| Frame size | 52-20-145 mm (lens width, bridge, arm length) |
| Lens depth | 43 mm |
| Designed for | Men, Women |
The 52mm lenses make this a medium frame that suits most faces. The 20mm bridge is wider than average, which suits a broader nose bridge. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 124mm.
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 6042
Pick the lenses that match your prescription:
- Single vision: one prescription for distance, reading or the computer.
- Progressive: near, middle and far in one lens with no line. (In the UK they call them varifocals.)
- Bifocal: a defined reading area at the bottom of the lens.
- Ready readers: simple magnification for close work.
At 43mm, the lens depth is deeper than most frames in our range, so progressive lenses have lots of room. Stronger prescription? A high-index lens keeps things thin and light. An anti-reflective, scratch-resistant coating is worth adding too, especially if you drive at night. Spend a lot of time on screens? This frame is also part of our blue light glasses range.
What you need to order
Have your prescription handy before you start. It will list the sphere, cylinder and axis for each eye, and often your PD as well. If your PD is missing, your optometrist can give it to you. Then simply choose your colour and lens type, enter your prescription and add any extras, such as a thinner lens or a coating. You can review everything in your cart before you pay.
How your glasses are made
Once you have picked your colour and lens type and entered your prescription and PD, our UK optical lab makes your lenses, fits them into your Synergy 6042 and sends the finished pair to you in Australia.
A little care goes a long way
Wipe your lenses with a microfibre cloth rather than the hem of your shirt, keep them in a case when they are in your bag, and never leave them on the dashboard on a hot day. Our lens care guide has a few more habits worth picking up.
Questions we often get
Can I get progressive lenses in the Synergy 6042?
Yes. The 43mm lens depth gives progressive lenses enough height for all three vision zones.
Can I wear the Synergy 6042 for driving?
Yes. Single vision or progressive lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 52-20-145: 52mm lens width, 20mm bridge and 145mm arms, a medium fit.
Will it suit a wider nose bridge?
Yes. The 20mm bridge is wider than most frames.
Is it unisex?
Yes. It suits men and women.
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.
