CK906

CK906 Prescription Glasses

A softly squared frame is one of the most versatile shapes around. The CK906 is a unisex full-rim soft square frame, sized 49-17-130, in Black, Pink or Dark Purple. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Carlton collection.

Choosing your CK906 colour

Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.

Pink. The Pink version is pink crystal. It is a gentle way to wear colour every day.

Dark Purple. Dark Purple keeps things simple. It adds a confident touch of colour and suits fair and cool skin tones.

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.

About the CK906 design

The softened corners suit round, oval and heart-shaped faces, adding a little shape without looking severe. A crystal front looks modern and light, and it goes with everything.

Whether it is your main pair or a spare, the CK906 is easy to live with.

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

With 49mm lenses, this is a compact frame that suits smaller faces. The 17mm bridge is average. The 130mm arms are a little shorter than standard. Across the lenses and bridge it measures about 115mm.

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 CK906

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 39mm lens depth gives varifocal lenses plenty of room. With a stronger prescription, a thinner high-index lens keeps the edges slim, and an anti-reflective coating cuts reflections from screens and street lights.

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

Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your CK906. Every pair is checked before it leaves us.

Looking after them

Clean your lenses with a microfibre cloth rather than your jumper, 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 CK906?

Yes. The 39mm lens depth gives varifocal lenses enough height for all three vision zones.

Is the CK906 comfortable for all-day wear?

Yes. It is a lightweight frame, and a thinner lens for a stronger prescription keeps the weight down even further.

Is it a small frame?

Yes. With 49mm lenses it suits smaller faces.

What does crystal mean?

A clear, see-through finish.

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.
