About the FLEXIT 6041
FLEXIT 6041 Prescription Glasses
If you want glasses that look smart and get out of the way, a rectangle is hard to beat. The FLEXIT 6041 is a unisex full-rim metal rectangular frame, sized 52-18-140, in Grey. You can order it with single vision, progressive or bifocal lenses made to your prescription. It is part of our Flexit range.
About the FLEXIT 6041 colour
Grey. Grey is a soft, neutral grey. It is cool, modern and understated, and it suits grey or silver hair especially well.
About the FLEXIT 6041 design
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 for an optician to adjust.
The FLEXIT 6041 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
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.
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.
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 6041
Pick the lenses that match your prescription:
- Single vision: one prescription for distance, reading or the computer.
- Progressive: near, middle and far in one lens with no line. (In the UK they call them varifocals.)
- Bifocal: a defined reading area at the bottom of the lens.
- Ready readers: simple magnification for close work.
The 33mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. 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.
What you need to order
Have your prescription handy before you start. It will list the sphere, cylinder and axis for each eye, and often your PD as well. If your PD is missing, your optometrist can give it to you. Then simply choose your colour and lens type, enter your prescription and add any extras, such as a thinner lens or a coating. You can review everything in your cart before you pay.
Made for you in our UK lab
Choose your colour and lenses, enter your prescription and PD, and our optical lab in the UK makes your lenses and fits them into your FLEXIT 6041 before sending them to you in Australia.
Looking after them
Clean the lenses with lens spray and a soft cloth, fold the arms before you put them down, and keep them in a hard case when they are not on your face. Our guide to caring for your lenses covers the rest.
FAQs
Is the FLEXIT 6041 suitable for progressive lenses?
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.
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.
