About the Chantelle Collection Chantelle 991
Chantelle 991 Prescription Glasses
A rounded square gives you the softness of a round frame with a little more structure. The Chantelle 991 is a unisex full-rim metal rounded square frame, sized 52-16-135, in Green or Purple. You can order it with single vision, varifocal or bifocal lenses made to your prescription.
Choosing your Chantelle 991 colour
Green. Green is an earthy green. It pairs well with neutrals, denim and earthy colours.
Purple. Purple is a rich purple. It adds a confident touch of colour and suits fair and cool skin tones.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Shape and style
The rounded corners and straight lines balance most face shapes, especially oval, square and heart-shaped faces. Metal lets the frame stay slim and light while keeping its shape.
The Chantelle 991 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
How it fits
| Brand | Chantelle Collection |
|---|---|
| Frame | Full Rim |
| Colours | Green, Purple |
| Frame size | 52-16-135 mm (lens width, bridge, arm length) |
| Lens depth | 35 mm |
| Effective diameter | 50 mm |
The 52mm lenses make this a medium frame that suits most faces. The 16mm bridge is on the narrow side. The 135mm arms are a standard length. Across the lenses and bridge it measures about 120mm.
To check the fit, look at the three numbers printed inside the arm of glasses you already own. If they are within two or three millimetres, this frame should feel similar.
Lens options for the Chantelle 991
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 35mm 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 to hand before you start. It shows the sphere, cylinder and axis for each eye, and sometimes your PD. If the PD is missing, your optician 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 basket before you pay.
From our lab to you
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Chantelle 991 and checked by our technicians before they are sent out.
A little care goes a long way
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.
FAQs
Can I get varifocal lenses in the Chantelle 991?
Yes. The 35mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the Chantelle 991 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 52-16-135: 52mm lens width, 16mm bridge and 135mm arms, a medium fit.
Will it suit a narrow nose?
Yes. The 16mm bridge is designed for slimmer noses.
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.
