About the FLEXIT 6038
FLEXIT 6038 Prescription Glasses
Some frames just suit almost everyone. Rounded squares are high on that list. The FLEXIT 6038 is a unisex full-rim metal rounded square frame, sized 53-18-140, in Bronze. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Flexit collection.
The colour
Bronze. Bronze is a warm, brownish metallic finish. It is a warm, elegant choice that pairs nicely with earthy colours.
Why you will like it
The rounded corners and straight lines balance most face shapes, especially oval, square and heart-shaped faces. The slim metal construction keeps it light and neat, and it is easy to adjust at an optical store.
If you want a frame you can put on in the morning and forget about, the FLEXIT 6038 is a strong choice.
Styling tips
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 | Bronze |
| Frame size | 53-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 36 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.
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 6038
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.
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.
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 6038. Every pair is checked before it leaves us.
Keep them looking new
Clean your lenses with a microfibre cloth rather than your sweater, keep them in their case when they are in your bag, and do not leave them on a sunny car dashboard. Our lens care guide has more tips.
Questions we often get
Can I get varifocal lenses in the FLEXIT 6038?
Yes. The 36mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the FLEXIT 6038 as computer glasses?
Yes. Single vision lenses set to your screen distance, or varifocals if you also need distance vision, both 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.
Who makes 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.
