About the Synergy 6019
Synergy 6019 Prescription Glasses
Round frames are having a moment, and the Synergy 6019 is an easy way to try the look. It is a full-rim plastic frame with a soft round shape, in black/brown or navy, and it suits men and women alike. It is sized 50-20-145 and has deep lenses that work beautifully with varifocals.
Black/brown or navy?
Black/brown starts with solid black across the top and melts into warm tortoiseshell at the bottom. It gives you the definition of black with the warmth of tortoiseshell, and it suits almost everyone.
Navy is a deep blue tortoiseshell with lighter flecks. It is a little more playful, and it looks great with blue eyes, grey hair and denim.
Details that make a difference
Small metal studs at the corners add a vintage touch, and the round shape softens angular features. It is a great frame for square and heart-shaped faces, and it adds a bit of character to oval faces too.
Why the lens depth matters
At 41mm, the lens depth on the Synergy 6019 is deeper than most frames in our range. That extra height gives varifocal lenses room for every vision zone, which makes reading and looking at screens feel more natural.
Size and fit
| Brand | Synergy |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Black/Brown, Navy |
| Frame size | 50-20-145 mm (lens width, bridge, arm length) |
| Lens depth | 41 mm |
| Designed for | Men, Women |
The 50mm lenses make this a compact frame, the 20mm bridge is wider than average, and the 145mm arms are on the longer side. That combination suits people with a broader nose bridge who still want a smaller frame.
Lens options for the Synergy 6019
Choose the lens type that suits how you use your glasses:
- Single vision: one prescription for distance, reading or the computer.
- Varifocal: near, middle and far in one lens with no line.
- Bifocal: a defined reading area at the bottom of the lens.
- Ready readers: simple magnification for close work.
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. You will also find it in our blue light glasses and reading glasses ranges.
Ordering online is easier than you think
All you need is a current prescription from your optician and your pupillary distance (PD), the distance between your pupils. Your PD is often written on your prescription; if it is not, ask your optician 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.
From our lab to you
Every pair is made to order. Our UK optical lab cuts your lenses to your prescription, fits them into your Synergy 6019 and checks every pair before it leaves our lab.
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.
Your questions, answered
Is the Synergy 6019 good for varifocal lenses?
Yes. The 41mm lens depth gives varifocal lenses lots of room.
Can I wear the Synergy 6019 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights and wet roads at night.
Is it unisex?
Yes. The round shape and classic colours suit men and women.
Will it suit a wide nose bridge?
Yes. The 20mm bridge is wider than average.
Where are my lenses made?
In our UK optical lab. They are cut to your prescription, fitted into your frame and checked before they are sent out.
