About the FLEXIT 6037
FLEXIT 6037 Prescription Glasses
A clean rectangular frame works at the office, at home and everywhere in between. The FLEXIT 6037 is a unisex full-rim metal rectangular frame, sized 55-17-140, in Gold or Dark Gun. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Flexit collection.
Gold or Dark Gun: which one is you?
Gold. Gold is a warm, soft gold. It brings warmth to the face and looks lovely with gold jewellery or a watch.
Dark Gun. The Dark Gun version is gunmetal. It is cool, modern and understated, and it suits grey or silver hair especially well.
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
Rectangular lenses suit round and oval faces, adding a bit of definition. The double bridge is a nod to classic aviator style and makes the front feel sturdy.
Metal lets the frame stay slim and light while keeping its shape.
Whether it is your main pair or a spare, the FLEXIT 6037 is easy to live with.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
Size and fit
| Brand | Flexit |
|---|---|
| Colours | Gold, Dark Gun |
| Frame size | 55-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 38 mm |
With 55mm lenses, this is a larger frame that suits wider faces. The 17mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 127mm.
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 FLEXIT 6037
Your optometrist’s prescription will usually tell you which of these you need:
- Varifocals if you want to see near and far without swapping glasses.
- Single vision for one task done well, such as driving, reading or screen work.
- Bifocals if you prefer a clearly defined reading area.
- Ready readers for straightforward close-up help.
The 38mm lens depth gives varifocal lenses plenty of room. 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.
What you will need
Have your prescription on hand before you start. It shows the sphere, cylinder and axis for each eye, and sometimes your PD. If the PD is missing, your optometrist can give it to you. Then choose your colour and lens type, enter your prescription and add any extras, such as thinner lenses or a coating. You can check everything in your cart before you pay.
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 6037 and checked by our technicians before they are sent out.
A little care goes a long way
Use lens spray and a soft cloth, fold the arms before putting your glasses down, and store them in a hard case. Our guide to looking after your lenses covers the rest.
FAQs
Can I get varifocal lenses in the FLEXIT 6037?
Yes. The 38mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the FLEXIT 6037 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 55mm lenses it suits wider faces.
What is a double bridge?
A second bar across the top of the frame, above the nose. It is a classic aviator detail.
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.
