About the Solo 583
Solo 583 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The Solo 583 is a unisex full-rim rectangular frame, sized 54-18-145, in Black, Grey or Demi. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Solo collection.
3 colours to choose from
Black. The Black version is black and crystal. It defines the eyes and goes with every outfit you own.
Grey. In Grey, the frame is translucent grey. It is a quiet, professional finish that works with navy, charcoal and white.
Demi. In Demi, the frame is tortoiseshell. It flatters warm and olive skin and works with almost any outfit.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
About the Solo 583 design
Rectangular lenses suit round and oval faces, adding a bit of definition. The crystal finish is clear and fresh, and it lets your features take centre stage.
The translucent finish lets light through, so the frame looks lighter and softer than a solid colour.
It is the kind of frame that works with most outfits, which makes the Solo 583 an easy pick for everyday wear.
Wearing it every day
Keep the rest of your look simple and let the frame do the talking. It works just as well with workwear as it does with weekend clothes.
How it fits
| Brand | Solo |
|---|---|
| Colours | Black, Grey, Demi |
| Frame size | 54-18-145 mm (lens width, bridge, arm length) |
| Lens depth | 35 mm |
The 54mm lenses put it at the upper end of medium. The 18mm bridge is average. The 145mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 126mm.
Not sure about sizing? Compare these numbers with the ones on the inside arm of a pair that fits you well. A difference of two or three millimetres or less usually means a similar fit.
Lens options for the Solo 583
Pick the lenses that match your prescription:
- 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.
The 35mm lens depth works with single vision, bifocal and many varifocal lenses. 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.
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 Solo 583 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.
Questions we often get
Can I get varifocal lenses in the Solo 583?
Yes. The 35mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the Solo 583 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.
What size is it?
It is size 54-18-145: 54mm lens width, 18mm bridge and 145mm arms, a medium fit.
What does crystal mean?
A clear, see-through finish.
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.
