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. You will find it in our Flexit collection.
Gold or Dark Gun?
Gold. Gold is a warm, soft gold. It gives a polished, classic finish that never looks loud.
Dark Gun. The Dark Gun version is gunmetal. It is a quiet, professional finish that works with navy, charcoal and white.
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.
About the FLEXIT 6037 design
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.
Styling tips
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 | 55-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 38 mm |
At 55mm per lens, it is a generous size, a good pick if standard frames feel tight. 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 optician’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. With a stronger prescription, a thinner high-index lens keeps the edges slim, and an anti-reflective coating cuts reflections from screens and street lights.
Ordering online is simple
You need a valid prescription from your optician and your pupillary distance (PD), the distance between your pupils. Many opticians include your PD on the prescription; if yours does not, just ask for it. Choose your colour, pick your lens type, enter your details and add any lens upgrades. If you are unsure about size, compare the measurements above with a pair you already wear.
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.
Looking after them
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.
Your questions, answered
Can I get varifocal lenses in the FLEXIT 6037?
Yes. The 38mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the FLEXIT 6037 comfortable for all-day wear?
Yes. It is a lightweight frame, and a thinner lens for a stronger prescription keeps the weight down even further.
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.
Who glazes my lenses?
Our own optical lab in the UK. Your lenses are made to your prescription and fitted into the frame before your glasses are sent to you.
