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 belongs to the Flexit range.
Black or Gun Metal: which one is you?
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Gun Metal. The Gun Metal version is gunmetal. It goes with almost everything and never draws too much attention.
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.
The details
Rectangular lenses suit round and oval faces, adding a bit of definition. Metal lets the frame stay slim and light while keeping its shape.
It is the kind of frame that works with most outfits, which makes the FLEXIT 6035 an easy pick for everyday wear.
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 | Black, Gun Metal |
| Frame size | 53-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 31 mm |
The 53mm lenses make this a medium frame that suits most faces. 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
Choose the lens type that suits how you use your glasses:
- 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. 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.
Made for you in our UK lab
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your FLEXIT 6035. Every pair is checked before it leaves us.
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.
Your questions, answered
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 wear the FLEXIT 6035 for driving?
Yes. Single vision lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 53-18-140: 53mm lens width, 18mm bridge and 140mm arms, a medium fit.
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.
