About the FLEXIT 6035
FLEXIT 6035 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The FLEXIT 6035 is a unisex full-rim metal rectangular frame, sized 53-18-140, in Black or Gun Metal. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Flexit range.
Black or Gun Metal: which one is you?
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Gun Metal. The Gun Metal version is gunmetal. It is cool, modern and understated, and it suits grey or silver hair especially well.
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.
Design details
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 6035 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
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.
How it fits
| Brand | Flexit |
|---|---|
| Colours | Black, Gun Metal |
| Frame size | 53-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 31 mm |
At 53mm 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 124mm.
The easiest way to check is against glasses you already love. Most frames show their size inside the arm; if yours are close to these, you are in safe territory.
Lens options for the FLEXIT 6035
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 31mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. 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
Your FLEXIT 6035 is glazed in our UK-based lab. Once you have chosen your lenses and entered your prescription, we cut and fit the lenses and check the finished glasses before they go out.
Keep them looking new
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
Is the FLEXIT 6035 suitable for varifocals?
The 31mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Can I use the FLEXIT 6035 as computer glasses?
Yes. Single vision lenses set to your screen distance work well for desk work.
What size is it?
It is size 53-18-140: 53mm lens width, 18mm bridge and 140mm arms, a medium fit.
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.
