About the Synergy 6047
Synergy 6047 Prescription Glasses
Square frames have a confident, modern look that works almost anywhere. The Synergy 6047 is a unisex full-rim plastic square frame, sized 51-19-145, in Grey or Navy. You can order it with single vision, progressive or bifocal lenses made to your prescription. You will find it in our Synergy range.
Grey or Navy: which one is you?
Grey. The Grey version is translucent grey. It is cool, modern and understated, and it suits grey or silver hair especially well.
Navy. Navy is a deep, dark blue. It reads as smart and dark from a distance, with a little more personality up close.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Shape and style
Square lenses add structure to round and oval faces and make features look more defined. The translucent finish lets light through, so the frame looks lighter and softer than a solid colour.
Small metal studs at the corners add a neat, vintage finishing touch. The thicker frame front gives it real presence on the face. 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 6047 is a strong choice.
How to wear it
It works with workwear and weekend clothes alike, which is exactly what you want from an everyday frame.
How it fits
| Brand | Synergy |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Grey, Navy |
| Frame size | 51-19-145 mm (lens width, bridge, arm length) |
| Lens depth | 42 mm |
| Designed for | Men, Women |
At 51mm per lens, it sits in the medium range, the most common adult fit. 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 121mm.
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 6047
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.
At 42mm, 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.
Ordering online is easier than you think
All you need is a current prescription from your optometrist and your pupillary distance (PD), the distance between your pupils. Your PD is often written on your prescription; if it is not, ask your optometrist for it. Pick your colour, choose your lens type, enter your details and add any lens upgrades. If you are not sure about sizing, compare the measurements above with a pair you already own. It only takes a minute and saves any guesswork.
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 6047 and then sends your glasses to you in Australia.
Looking after them
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.
