About the Planet+18
Planet+18 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The Planet+18 is a women’s full-rim plastic rectangular frame in Black/Brown, Dark Blue/Light Blue or Black/Purple. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Planet+ range.
Which colour is you?
Black/Brown. In Black/Brown, the frame is black and brown. It defines the eyes and goes with every outfit you own.
Dark Blue/Light Blue. In Dark Blue/Light Blue, the frame is dark blue and light blue. It reads as smart and dark from a distance, with a little more personality up close.
Black/Purple. In Black/Purple, the frame is black and purple. It is the safest choice if you only want one pair, and it never looks out of place.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
About the Planet+18 design
Rectangular lenses suit round and oval faces, adding a bit of definition. A contrasting colour on the inside of the frame adds a flash of personality that you only see up close.
Plastic keeps the weight down and allows richer, deeper colour than metal.
If you want a frame you can put on in the morning and forget about, the Planet+18 is a strong choice.
How to wear it
For work, pair it with a crisp shirt or blazer. At the weekend it looks just as good with a T-shirt and jeans.
Frame size and fit
| Brand | Planet+ |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Black/Brown, Dark Blue/Light Blue, Black/Purple |
| Designed for | Women |
The 51mm lenses make this a medium frame that suits most faces.
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 Planet+18
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.
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.
Made for you in our UK lab
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your Planet+18. 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.
FAQs
Can I wear the Planet+18 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
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.
