About the FLEXIT 6041
FLEXIT 6041 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The FLEXIT 6041 is a unisex full-rim metal rectangular frame, sized 52-18-140, in Grey. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Flexit collection.
Colour and finish
Grey. Grey is a soft, neutral grey. It goes with almost everything and never draws too much attention.
Why you will like it
Rectangular lenses suit round and oval faces, adding a bit of definition. The slim metal construction keeps it light and neat, and it is easy to adjust at an optical store.
Whether it is your main pair or a spare, the FLEXIT 6041 is easy to live with.
How to wear it
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.
Frame size and fit
| Brand | Flexit |
|---|---|
| Colours | Grey |
| Frame size | 52-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 33 mm |
At 52mm per lens, it sits in the medium range, the most common adult fit. The 18mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 122mm.
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 6041
Pick the lenses that match your prescription:
- 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 33mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. Want lighter lenses? A high-index lens is thinner than standard plastic. Pair it with an anti-reflective coating for less glare when you drive after dark.
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 6041 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.
Everyday wear
Good everyday glasses should be comfortable from breakfast to bedtime. Light materials, a secure fit and a classic look all help, and this frame ticks those boxes. Add the right lenses and it will handle screens, reading and driving with ease.
FAQs
Is the FLEXIT 6041 suitable for varifocals?
The 33mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Can I use the FLEXIT 6041 as computer glasses?
Yes. Single vision lenses set to your screen distance work well for desk work.
What size is it?
It is size 52-18-140: 52mm lens width, 18mm bridge and 140mm arms, a medium fit.
Where are my lenses made?
