About the Synergy 6051
Synergy 6051 Prescription Glasses
Some frames just suit almost everyone. Rounded squares are high on that list. The Synergy 6051 is a unisex full-rim plastic rounded square frame, sized 52-19-140, in Brown or Teal. You can order it with single vision, progressive or bifocal lenses made to your prescription. You will find it in our Synergy range.
Choosing your Synergy 6051 colour
Brown. Brown is a warm, earthy brown. It flatters warm and olive skin and works with almost any outfit.
Teal. In Teal, the frame is translucent teal. It is unusual without being loud, and it looks fantastic with red, auburn or dark hair.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Design details
The rounded corners and straight lines balance most face shapes, especially oval, square and heart-shaped faces. The translucent finish lets light through, so the frame looks lighter and softer than a solid colour.
It is a bolder frame, so it makes a statement without trying too hard. Plastic keeps the weight down and allows richer, deeper colour than metal.
The Synergy 6051 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
Styling tips
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.
How it fits
| Brand | Synergy |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Brown, Teal |
| Frame size | 52-19-140 mm (lens width, bridge, arm length) |
| Lens depth | 43 mm |
| Designed for | Men, Women |
At 52mm per lens, it sits in the medium range, the most common adult fit. The 19mm bridge is a little wider than average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 123mm.
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 6051
Choose the lens type that suits how you use your glasses:
- 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.
At 43mm, the lens depth is deeper than most frames in our range, so progressive lenses have lots 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.
Before you order
Check that your prescription is current; an eye test every couple of years is a good habit, and your optometrist 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.
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 6051 and sends the finished pair to you in Australia.
Keep them looking new
Clean the lenses with lens spray and a soft cloth, fold the arms before you put them down, and keep them in a hard case when they are not on your face. Our guide to caring for your lenses covers the rest.
FAQs
Can I get progressive lenses in the Synergy 6051?

Can I wear the Synergy 6051 for driving?
Yes. Single vision or progressive lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
