About the Original Penguin The Finn
The Finn Prescription Glasses
A round frame is an easy way to add a little character. The Finn is a men’s full-rim round frame, sized 48-21-140, in Blue, Brown or Green. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Original Penguin range.
Which colour is you?
Blue. The Blue version is striped blue. It reads as smart and dark from a distance, with a little more personality up close.
Brown. The Brown version is striped brown. It flatters warm and olive skin and works with almost any outfit.
Green. The Green version is translucent green. It is unusual without being loud, and it looks fantastic with red, auburn or dark hair.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Shape and style
Round frames soften angular features, so they are a great match for square and heart-shaped faces. The translucent finish lets light through, so the frame looks lighter and softer than a solid colour.
The striped finish adds texture that changes as the light catches it.
Whether it is your main pair or a spare, The Finn is easy to live with. Thinking of a second pair? The Finn works well as a backup.
Styling tips
Choose the darker colour for the office and the lighter one for a more relaxed look. Either way, it is an easy frame to wear every day.
Size and fit
| Brand | Original Penguin |
|---|---|
| Frame | Full Rim |
| Colours | Blue, Brown, Green |
| Frame size | 48-21-140 mm (lens width, bridge, arm length) |
| Designed for | Men |
With 48mm lenses, this is a compact frame that suits smaller faces. The 21mm bridge is wider than average, which suits a broader nose bridge. The 140mm arms are a standard length. Across the lenses and bridge it measures about 117mm.
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 Finn
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.
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
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your The Finn and checked by our technicians before they are sent out.
Keep them looking new
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 48mm lenses it suits smaller faces.
Is The Finn 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.
Will it suit a wider nose bridge?
Yes. The 21mm bridge is wider than most frames.
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.
