About the Planet 46
Planet 46 Prescription Glasses
A clean rectangular frame works at the office, at home and everywhere in between. The Planet 46 is a unisex full-rim plastic rectangular frame in Tortoise, Black or Matt Black. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Planet range.
3 colours to choose from
Tortoise. Tortoise is a classic tortoiseshell. It is a classic option that goes with almost anything.
Black. Black is a deep, solid black. It is the safest choice if you only want one pair, and it never looks out of place.
Matt Black. Matt Black is a soft, non-shiny black. It is the safest choice if you only want one pair, and it never looks out of place.
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.
Shape and style
Rectangular lenses suit round and oval faces, adding a bit of definition. Plastic keeps the weight down and allows richer, deeper colour than metal.
Whether it is your main pair or a spare, the Planet 46 is easy to live with.
Styling tips
It works with workwear and weekend clothes alike, which is exactly what you want from an everyday frame.
How it fits
| Brand | Planet |
|---|---|
| Frame | Full Rim, Plastic |
| Colours | Tortoise, Black, Matt Black |
| Designed for | Unisex |
With 47mm 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 46
Pick the lenses that match your prescription:
- 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.
Want lighter lenses? A high-index lens is thinner than standard plastic. Pair it with an anti-reflective coating for less glare when you drive after dark.
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 46. Every pair is checked before it leaves us.
Looking after them
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.
Your questions, answered
Is it a small frame?
Yes. With 47mm lenses it suits smaller faces.
Is the Planet 46 comfortable for all-day wear?
Yes. It is a lightweight frame, and a thinner lens for a stronger prescription keeps the weight down even further.
Is it unisex?
Yes. It suits men and women.
What is havana or tortoiseshell?
A mottled pattern of browns and ambers, a classic eyewear finish.
Who glazes my lenses?
Our own optical lab in the UK. Your lenses are made to your prescription and fitted into the frame before your glasses are sent to you.
