About the Planet 79
Planet 79 Prescription Glasses
Flat edges and angles turn a simple frame into a talking point. The Planet 79 is a unisex full-rim plastic geometric frame in Blue, Matt Black or Brown. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Planet collection.
Choosing your Planet 79 colour
Blue. Blue is a clear, easy-to-wear blue. It is a fresh alternative to black that still looks professional.
Matt Black. Matt Black is a soft, non-shiny black. It defines the eyes and goes with every outfit you own.
Brown. The Brown version is translucent brown. 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
The angular shape suits round and oval faces, where it adds definition and interest. The translucent finish lets light through, so the frame looks lighter and softer than a solid colour.
The plastic frame is light on the nose and comfortable for all-day wear.
The Planet 79 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
Styling tips
Because it is unisex, it is easy to share the look across the household. Pick the colour that matches your wardrobe rather than worrying about who it is designed for.
How it fits
| Brand | Planet |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Blue, Matt Black, Brown |
| Designed for | Unisex |
With 59mm lenses, this is a larger frame that suits wider 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 79
Choose the lens type that suits how you use your glasses:
- Varifocals if you want to see near and far without swapping glasses.
- Single vision for one task done well, such as driving, reading or screen work.
- Bifocals if you prefer a clearly defined reading area.
- Ready readers for straightforward close-up help.
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.
Before you order
Make sure your prescription is in date; most adults in the UK are advised to have an eye test every two years, and your optician will tell you if you need one sooner. You will also need your PD, which tells our lab where to centre the lenses. With those two things ready, ordering takes a few minutes: choose your colour, pick your lenses, enter your details and you are done.
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 Planet 79. Every pair is checked before it leaves us.
Looking after them
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.
Questions we often get
Is it a large frame?
Yes. With 59mm lenses it suits wider faces.
Can I wear the Planet 79 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
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.
