About the Planet 68
Planet 68 Prescription Glasses
A round frame is an easy way to add a little character. The Planet 68 is a unisex full-rim plastic round frame in Matt Black, Shiny Black or Tortoise. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Planet range.
Which colour is you?
Matt Black. Matt Black is a soft, non-shiny black. It looks sharp at work and just as good with jeans at the weekend.
Shiny Black. Shiny Black is a good everyday shade. It looks sharp at work and just as good with jeans at the weekend.
Tortoise. Tortoise is a classic tortoiseshell. It is a classic option that goes with almost anything.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Design details
Round frames soften angular features, so they are a great match for square and heart-shaped faces. A crystal front looks modern and light, and it goes with everything.
Plastic keeps the weight down and allows richer, deeper colour than metal.
It is the kind of frame that works with most outfits, which makes the Planet 68 an easy pick for everyday wear.
How to wear it
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 | Matt Black, Shiny Black, Tortoise |
| Designed for | Unisex |
With 50mm lenses, this is a compact frame that suits smaller faces.
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 Planet 68
Your optician’s prescription will usually tell you which of these you need:
- 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.
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
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your Planet 68 and checked by our technicians before they are sent out.
Keep them looking new
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
