About the Sakuru SAK1020T
SAK1020T Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The SAK1020T is a unisex full-rim metal rectangular frame, sized 52-17-140, in Black or Blue. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Sakuru range.
Choosing your SAK1020T colour
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Blue. Blue is a clear, easy-to-wear blue. It brings a cool, calm touch of colour that suits most 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.
Design details
Rectangular lenses suit round and oval faces, adding a bit of definition. The tortoiseshell arms pair nicely with the front and give the frame a relaxed feel.
The slim metal construction keeps it light and neat, and it is easy for an optician to adjust.
Whether it is your main pair or a spare, the SAK1020T is easy to live with.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
How it fits
| Brand | Sakuru |
|---|---|
| Colours | Black, Blue |
| Frame size | 52-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 35 mm |
The 52mm lenses make this a medium frame that suits most faces. The 17mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 121mm.
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 SAK1020T
Your optician’s prescription will usually tell you which of these you need:
- 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.
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 SAK1020T. Every pair is checked before it leaves us.
A little care goes a long way
Use lens spray and a soft cloth, fold the arms before putting your glasses down, and store them in a hard case. Our guide to looking after your lenses covers the rest.
Questions we often get
Can I get varifocal lenses in the SAK1020T?
Yes. The 35mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the SAK1020T 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 52-17-140: 52mm lens width, 17mm bridge and 140mm arms, a medium fit.
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.
