About the Universal Eyewear Collection Universal Eyewear Carla Stainless Steel
Universal Eyewear Carla Stainless Steel Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The Universal Eyewear Carla Stainless Steel is a unisex semi-rimless metal rectangular frame, sized 51-18-130, in Black, Lilac or Pink. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Universal Eyewear Collection.
Which colour is you?
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Lilac. Lilac is a soft, pale purple. It adds a confident touch of colour and suits fair and cool skin tones.
Pink. The Pink version is rose. It is a gentle way to wear colour every day.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Shape and style
Rectangular lenses suit round and oval faces, adding a bit of definition. Being semi-rimless, it keeps a defined top line while the lower half of the lens stays open and light.
Decorative arms give the frame a finished, designer feel when you see it side on. A patterned front adds personality while still being easy to wear. Metal lets the frame stay slim and light while keeping its shape.
If you want a frame you can put on in the morning and forget about, the Universal Eyewear Carla Stainless Steel is a strong choice. The Universal Eyewear Carla Stainless Steel is an easy frame to wear every day.
How to wear it
Choose the colour closest to what you wear most and it will go with almost everything.
Size and fit
| Brand | Universal Eyewear Collection |
|---|---|
| Frame | Semi-rimless |
| Colours | Black, Lilac, Pink |
| Frame size | 51-18-130 mm (lens width, bridge, arm length) |
| Lens depth | 30 mm |
| Effective diameter | 54 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 18mm bridge is average. The 130mm arms are a little shorter than standard. Across the lenses and bridge it measures about 120mm.
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 Universal Eyewear Carla Stainless Steel
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.
The 30mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. 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.
Made for you in our UK lab
Your Universal Eyewear Carla Stainless Steel 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
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.
FAQs
Is the Universal Eyewear Carla Stainless Steel suitable for varifocals?
The 30mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Is the Universal Eyewear Carla Stainless Steel 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 51-18-130: 51mm lens width, 18mm bridge and 130mm arms, a medium fit.
What does semi-rimless mean?
The frame runs along the top of the lenses only. The lower edge is held by a fine line, so the bottom of the lens is open.
Do you make the lenses yourselves?
Yes. Every pair is made to order in our UK optical lab, where your lenses are cut to your prescription and fitted into your frame.
