About the FLEXIT 6042
FLEXIT 6042 Prescription Glasses
A clean rectangular frame works at the office, at home and everywhere in between. 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 is part of our Flexit collection.
Blue/Silver or Bronze/Gold?
Blue/Silver. Blue/Silver pairs blue with silver. It goes with almost everything and never draws too much attention.
Bronze/Gold. Bronze/Gold mixes bronze and gold. It brings warmth to the face and looks lovely with gold jewellery or a watch.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
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 for an optician to adjust.
It is the kind of frame that works with most outfits, which makes the FLEXIT 6042 an easy pick for everyday wear.
Wearing it every day
Choose the colour closest to what you wear most and it will go with almost everything.
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 |
The 52mm lenses make this a medium frame that suits most faces. 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
Pick the lenses that match your prescription:
- 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. 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.
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
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your FLEXIT 6042. Every pair is checked before it leaves us.
Looking after them
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.
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.
