About the Planet 72
Planet 72 Prescription Glasses
If round and square both feel too ordinary, try a geometric shape. The Planet 72 is a unisex full-rim plastic geometric frame in Clear, Black or Puprle Mix. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Planet range.
Which colour is you?
Clear. The Clear version is crystal clear. It blends in rather than stands out, which many people find easy to wear every day.
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Puprle Mix. Puprle Mix is easy to wear. It is a classic option that goes with almost anything.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Why you will like it
The angular shape suits round and oval faces, where it adds definition and interest. The crystal finish is clear and fresh, and it lets your features take centre stage.
Tortoiseshell arms add warmth and a classic finishing touch. A patterned front adds personality while still being easy to wear. Plastic keeps the weight down and allows richer, deeper colour than metal.
Whether it is your main pair or a spare, the Planet 72 is easy to live with.
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.
Size and fit
| Brand | Planet |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Clear, Black, Puprle Mix |
| Designed for | Unisex |
At 52mm per lens, it sits in the medium range, the most common adult fit.
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 72
Choose the lens type that suits how you use your glasses:
- 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.
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.
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 Planet 72. Every pair is checked before it leaves us.
A little care goes a long way
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.
Your questions, answered
Is it unisex?
Yes. It suits men and women.
Can I use the Planet 72 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 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.
