About the Retro Collection Retro Sun 036
Retro Sun 036 Prescription Sunglasses
If you wear glasses, prescription sunglasses are the easiest upgrade you can make. The Retro Sun 036 is a pair of unisex full-rim square sunglasses, sized 50-19-145, in Crystal, Grey or Sage. It can be made with your prescription, so you can see clearly and keep the sun out at the same time. It belongs to the Retro Collection.
Choosing your Retro Sun 036 colour
Crystal. Crystal is a clear, see-through finish. It is shown with grey lenses. It blends in rather than stands out, which many people find easy to wear every day.
Grey. Grey is a soft, neutral grey. It is shown with grey lenses. It is a quiet, professional finish that works with navy, charcoal and white.
Sage. Sage is easy to wear. It is shown with grey lenses. It feels fresh and a little bit different, which is exactly why people notice it.
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
Square lenses add structure to round and oval faces and make features look more defined. The crystal finish is clear and fresh, and it lets your features take centre stage.
The Retro Sun 036 is an easy everyday pair of prescription sunglasses for driving, walking and weekends outdoors.
How to wear it
Keep a pair in the car and another in your bag and you will never squint at the glare again.
Size and fit
| Brand | Retro Collection |
|---|---|
| Frame | Full Rim |
| Colours | Crystal, Grey, Sage |
| Frame size | 50-19-145 mm (lens width, bridge, arm length) |
| Lens depth | 40 mm |
| Effective diameter | 50 mm |
With 50mm lenses, this is a compact frame that suits smaller faces. The 19mm bridge is a little wider than average. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 119mm.
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 Retro Sun 036
The Retro Sun 036 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 40mm 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.
What you will need
Have your prescription to hand before you start. It shows the sphere, cylinder and axis for each eye, and sometimes your PD. If the PD is missing, your optician can give it to you. Then choose your colour and lens type, enter your prescription and add any extras, such as thinner lenses or a coating. You can check everything in your basket before you pay.
How your glasses are made
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your Retro Sun 036. Every pair is checked before it leaves us.
A little care goes a long way
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.
Questions we often get
Can I get the Retro Sun 036 with my prescription?
Yes. Choose single vision, varifocal, bifocal or ready reader lenses when you order.
Can I get varifocal lenses in the Retro Sun 036?
Yes. The 40mm lens depth gives varifocal lenses enough height for all three vision zones.
Is it a small frame?
Yes. With 50mm lenses it suits smaller faces.
What does crystal mean?
A clear, see-through 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.
