About the Planet+20
Planet+20 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The Planet+20 is a unisex full-rim plastic rectangular frame in Navy, Black or Brown/Green. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Planet+ collection.
Which colour is you?
Navy. The Navy version is dark navy. It looks great with blue or grey eyes and pairs easily with denim and white.
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Brown/Green. The Brown/Green version is brown and green. It is a classic that looks relaxed and a little bit vintage.
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.
Design details
Rectangular lenses suit round and oval faces, adding a bit of definition. The plastic frame is light on the nose and comfortable for all-day wear.
If you want a frame you can put on in the morning and forget about, the Planet+20 is a strong choice.
Wearing it every day
It works with workwear and weekend clothes alike, which is exactly what you want from an everyday frame.
Frame size and fit
| Brand | Planet+ |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Navy, Black, Brown/Green |
| Designed for | Unisex |
At 56mm per lens, it is a generous size, a good pick if standard frames feel tight.
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 Planet+20
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.
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.
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 Planet+20. 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.
Who it is for
This frame is a good fit for anyone who wants reliable everyday glasses without fuss. It works for long days at a desk, the school run, driving and catching up with friends, and it pairs with most wardrobes. If you are replacing an old pair, compare the measurements above with the glasses you wear now.
FAQs
Is it a large frame?
Yes. With 56mm lenses it suits wider faces.
Can I use the Planet+20 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.
Is it unisex?
Yes. It suits men and women.
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.
