About the FLEXIT 6042
FLEXIT 6042 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The FLEXIT 6042 is a unisex full-rim metal rectangular frame, sized 52-18-135, in Blue/Silver or Bronze/Gold. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Flexit range.
Choosing your FLEXIT 6042 colour
Blue/Silver. Blue/Silver mixes blue and silver. It is cool, modern and understated, and it suits grey or silver hair especially well.
Bronze/Gold. Bronze/Gold mixes bronze and gold. It suits warm and olive skin tones beautifully.
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.
Why you will like it
Rectangular lenses suit round and oval faces, adding a bit of definition. Metal lets the frame stay slim and light while keeping its shape.
The FLEXIT 6042 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.
How it fits
| Brand | Flexit |
|---|---|
| Colours | Blue/Silver, Bronze/Gold |
| Frame size | 52-18-135 mm (lens width, bridge, arm length) |
| Lens depth | 36 mm |
At 52mm per lens, it sits in the medium range, the most common adult fit. The 18mm bridge is average. The 135mm arms are a standard length. Across the lenses and bridge it measures about 122mm.
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 6042
Choose the lens type that suits how you use your glasses:
- Single vision: the same prescription from edge to edge.
- Bifocal: distance at the top and a reading segment at the bottom.
- Varifocal: a smooth change from distance to reading, with no line.
- Ready readers: a fixed magnification for books, phones and screens.
The 36mm lens depth works with single vision, bifocal and many varifocal lenses. 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
Your FLEXIT 6042 is made 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
Rinse off any grit before you wipe, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay aligned. See our lens care guide for more.
Questions we often get
Can I get varifocal lenses in the FLEXIT 6042?
Yes. The 36mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the FLEXIT 6042 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 52-18-135: 52mm lens width, 18mm bridge and 135mm 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.
