The Justin

The Justin Prescription Glasses

Square frames have a confident, modern look that works almost anywhere. The Justin is a men’s full-rim square frame, sized 50-21-145, in Black, Blue or Tort. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Original Penguin range.

Choosing your The Justin colour

Black. In Black, the frame is black that fades to clear. It is the safest choice if you only want one pair, and it never looks out of place.

Blue. The Blue version is blue that fades to clear. It is a fresh alternative to black that still looks professional.

Tort. In Tort, the frame is tortoiseshell. It flatters warm and olive skin and works with almost any outfit.

If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.

Design details

Square lenses add structure to round and oval faces and make features look more defined. A soft colour fade defines the brow line and lets the lower half of the frame melt away.

It is the kind of frame that works with most outfits, which makes The Justin an easy pick for everyday wear.

How to wear it

Short hair and a clean shave make the frame shape stand out; with longer hair or a beard it reads as more relaxed.

Size and fit

At 50mm per lens, it is on the smaller side, which is ideal if most frames feel too wide. The 21mm bridge is wider than average, which suits a broader nose bridge. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 121mm.

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 Justin

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.

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.

Made for you in our UK lab

Your The Justin is glazed in our UK-based lab. Once you have chosen your lenses and entered your prescription, we cut and fit the lenses and check the finished glasses before they go out.

Looking after them

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.

FAQs

Is it a small frame?

Yes. With 50mm lenses it suits smaller faces.

Can I wear The Justin for driving?

Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.

Will it suit a wider nose bridge?

Yes. The 21mm bridge is wider than most frames.

What does the colour fade look like?

The colour is darker at the top of the frame and becomes lighter towards the bottom.

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.
