About the FLEXIT 6046
FLEXIT 6046 Prescription Glasses
If you want glasses that look sharp and get out of the way, a rectangle is hard to beat. The FLEXIT 6046 is a unisex full-rim metal rectangular frame, sized 57-19-145, in Gold or Dark Gun. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Flexit collection.
Gold or Dark Gun: which one is you?
Gold. Gold is a warm, soft gold. It gives a polished, classic finish that never looks loud.
Dark Gun. In Dark Gun, the frame is gunmetal. It is a great match for cooler skin tones and a crisp, tidy look.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Why you will like it
Rectangular lenses suit round and oval faces, adding a bit of definition. Metal lets the frame stay slim and light while keeping its shape.
If you want a frame you can put on in the morning and forget about, the FLEXIT 6046 is a strong choice.
Wearing it every day
Keep the rest of your look simple and let the frame do the talking. It works just as well with workwear as it does with weekend clothes.
How it fits
| Brand | Flexit |
|---|---|
| Colours | Gold, Dark Gun |
| Frame size | 57-19-145 mm (lens width, bridge, arm length) |
| Lens depth | 37 mm |
With 57mm lenses, this is a larger frame that suits wider 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 133mm.
Not sure about sizing? Compare these numbers with the ones on the inside arm of a pair that fits you well. A difference of two or three millimetres or less usually means a similar fit.
Lens options for the FLEXIT 6046
Your optometrist’s prescription will usually tell you which of these you need:
- Single vision: one prescription across the whole lens, for distance, reading or the computer.
- Varifocal: near, intermediate and distance in one lens, with no visible line.
- Bifocal: a separate reading segment in the lower part of the lens.
- Ready readers: simple magnification if you just need help with close work.
The 37mm lens depth works with single vision, bifocal and many varifocal lenses. If your prescription is high, a high-index lens keeps things thin. An anti-reflective, scratch-resistant coating is a sensible extra for everyday wear.
Before you order
Make sure your prescription is in date; most adults in Canada are advised to have an eye exam every two years, and your optometrist will tell you if you need one sooner. You will also need your PD, which tells our lab where to centre the lenses. With those two things ready, ordering takes a few minutes: choose your colour, pick your lenses, enter your details and you are done.
How your glasses are made
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your FLEXIT 6046 and checked by our technicians before they are sent out.
Keep them looking new
Rinse off any grit before you wipe, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay aligned. See our lens care guide for more.
FAQs
Can I get varifocal lenses in the FLEXIT 6046?
Yes. The 37mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the FLEXIT 6046 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
Is it a large frame?
Yes. With 57mm lenses it suits wider faces.
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.
