Choosing your Paul Costelloe Sun 108 colour
Brown. Brown is a warm, earthy brown. It is shown with gradient lenses. It is softer than black and suits brown, auburn and red hair.
Dark Blue. Dark Blue is a deep ink blue. It reads as smart and dark from a distance, with a little more personality up close.
Navy. Navy is a deep, dark blue. It is shown with grey lenses. It reads as smart and dark from a distance, with a little more personality up close.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Shape and style

Keep the Paul Costelloe Sun 108 in the car, take it to the beach or wear it on your lunch break; it is ready for bright summer days.
How to wear it
Easy to wear with almost anything, from beachwear to a smart jacket.
Size and fit
| Brand | Paul Costelloe Collection |
|---|---|
| Frame | Full Rim |
| Colours | Brown, Dark Blue, Navy |
| Frame size | 55-17-140 mm (lens width, bridge, arm length) |
| Lens depth | 42 mm |
| Effective diameter | 57 mm |
With 55mm lenses, this is a larger frame that suits wider faces. The 17mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 127mm.
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.
Prescription lenses for the Paul Costelloe Sun 108
The Paul Costelloe Sun 108 can be made with any of these lens types:
- 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.
At 42mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. 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.
How your glasses are made
Your Paul Costelloe Sun 108 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.
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.
