About the Synergy 6050
Synergy 6050 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The Synergy 6050 is a unisex full-rim plastic rectangular frame, sized 52-19-145, in Black or Crystal. 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 Crystal: which one is you?
Black. Black is a deep, solid black. It looks sharp at work and just as good with jeans at the weekend.
Crystal. The Crystal version is crystal clear. It blends in rather than stands out, which many people find easy to wear every day.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
About the Synergy 6050 design
Rectangular lenses suit round and oval faces, adding a bit of definition. A crystal front looks modern and light, and it goes with everything.
The thicker frame front gives it real presence on the face. The plastic frame is light on the nose and comfortable for all-day wear.
If you want a frame you can put on in the morning and forget about, the Synergy 6050 is a strong choice.
Styling tips
It works with workwear and weekend clothes alike, which is exactly what you want from an everyday frame.
Size and fit
| Brand | Synergy |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Black, Crystal |
| Frame size | 52-19-145 mm (lens width, bridge, arm length) |
| Lens depth | 39 mm |
| Designed for | Men, Women |
The 52mm 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 123mm.
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 6050
Your optometrist’s prescription will usually tell you which of these you need:
- Progressive 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.
The 39mm lens depth gives progressive lenses plenty of room. 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. 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
Every pair is made to order. Our UK optical lab cuts your lenses to your prescription, fits them into your Synergy 6050 and then sends your glasses to you in Australia.
Keep them looking new
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 6050?
Yes. The 39mm lens depth gives progressive lenses enough height for all three vision zones.
Can I use the Synergy 6050 as computer glasses?
Yes. Single vision lenses set to your screen distance, or progressive lenses if you also need distance vision, both work well for desk work.
What size is it?
It is size 52-19-145: 52mm lens width, 19mm bridge and 145mm arms, a medium fit.
Is it unisex?
Yes. It suits men and women.
What does crystal mean?
A clear, see-through finish.
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.
