About the Synergy 6018
Synergy 6018 Prescription Glasses
Square frames have a confident, modern look that works almost anywhere. The Synergy 6018 is a unisex full-rim plastic square frame, sized 51-20-145, in Havana/Black or Matt Black/Grey. You can order it with single vision, progressive or bifocal lenses made to your prescription. It belongs to the Synergy range.
Havana/Black or Matt Black/Grey?
Havana/Black. The Havana/Black version is havana tortoiseshell. It defines the eyes and goes with every outfit you own.
Matt Black/Grey. In Matt Black/Grey, the frame is matte black. It defines the eyes and goes with every outfit you own.
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.
Why you will like it
Square lenses add structure to round and oval faces and make features look more defined. Decorative arms give the frame a finished, designer feel when you see it side on.
A patterned front adds personality while still being easy to wear. A matte finish gives the frame a soft, contemporary look. 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 6018 is a strong choice.
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.
Frame size and fit
| Brand | Synergy |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Havana/Black, Matt Black/Grey |
| Frame size | 51-20-145 mm (lens width, bridge, arm length) |
| Lens depth | 37 mm |
| Designed for | Men, Women |
At 51mm per lens, it sits in the medium range, the most common adult fit. 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 122mm.
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 6018
Choose the lens type that suits how you use your glasses:
- 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.
The 37mm lens depth works with single vision, bifocal and many progressive lenses. Prefer to keep things slim? Choose a high-index lens, which is thinner and lighter than standard. Then add an anti-reflective coating to cut glare from headlights and screens. 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 6018 and sends the finished pair to you in Australia.
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.
