About the Retro Collection Retro Sun 042
Retro Sun 042 Prescription Sunglasses
Good sunglasses keep the glare out. Prescription ones let you see the view as well. The Retro Sun 042 is a pair of unisex full-rim square sunglasses, sized 54-17-145, in Black, Brown or Grey. It can be made with your prescription, so you can see clearly and keep the sun out at the same time. You will find it in our Retro Collection.
Which colour is you?
Black. Black is a deep, solid black. It is shown with gradient lenses. It looks sharp at work and just as good with jeans at the weekend.
Brown. The Brown version is brown crystal. It is shown with gradient lenses. It flatters warm and olive skin and works with almost any outfit.
Grey. Grey is a soft, neutral grey. It is shown with gradient lenses. It goes with almost everything and never draws too much attention.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
About the Retro Sun 042 design
Square lenses add structure to round and oval faces and make features look more defined. A crystal front looks modern and light, and it goes with everything.
Keep the Retro Sun 042 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
Keep a pair in the car and another in your bag and you will never squint at the glare again.
Frame size and fit
| Brand | Retro Collection |
|---|---|
| Frame | Full Rim |
| Colours | Black, Brown, Grey |
| Frame size | 54-17-145 mm (lens width, bridge, arm length) |
| Lens depth | 39 mm |
| Effective diameter | 53 mm |
The 54mm lenses put it at the upper end of medium. The 17mm bridge is average. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 125mm.
To check the fit, look at the three numbers printed inside the arm of glasses you already own. If they are within two or three millimetres, this frame should feel similar.
Prescription lenses for the Retro Sun 042
The Retro Sun 042 can be made with any of these lens types:
- 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.
The 39mm lens depth gives varifocal lenses plenty of room. 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
Your Retro Sun 042 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.
