About the Meridian Eyewear Collection Meridian Eyewear Potenza
Meridian Eyewear Potenza Prescription Glasses
There is a reason square glasses never really go out of fashion. The Meridian Eyewear Potenza is a unisex full-rim square frame, sized 60-19-145, in Black Gradual, Blue Gradual or Brown Gradual. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Meridian Eyewear Collection.
3 colours to choose from
Black Gradual. Black Gradual is a good everyday shade. It looks sharp at work and just as good with jeans at the weekend.
Blue Gradual. Blue Gradual is a blue that fades gently towards the bottom. It looks great with blue or grey eyes and pairs easily with denim and white.
Brown Gradual. Brown Gradual is a good everyday shade. It flatters warm and olive skin and works with almost any outfit.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Design details
Square lenses add structure to round and oval faces and make features look more defined. The colour fades from darker at the top to lighter at the bottom, which gives the frame depth and keeps it from looking heavy.
The Meridian Eyewear Potenza is a great everyday frame: smart enough for work and relaxed enough for the weekend.
Styling tips
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 | Meridian Eyewear Collection |
|---|---|
| Frame | Full Rim |
| Colours | Black Gradual, Blue Gradual, Brown Gradual |
| Frame size | 60-19-145 mm (lens width, bridge, arm length) |
| Lens depth | 44 mm |
| Effective diameter | 58 mm |
With 60mm lenses, this is a larger frame that suits wider 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 139mm.
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.
Lens options for the Meridian Eyewear Potenza
Pick the lenses that match your prescription:
- Single vision: one prescription across the whole lens, for distance, reading or the computer.
- Varifocal: near, intermediate and distance in one lens, with no visible line.
- Bifocal: a separate reading segment in the lower part of the lens.
- Ready readers: simple magnification if you just need help with close work.
At 44mm, 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.
Ordering online is simple
You need a valid prescription from your optician and your pupillary distance (PD), the distance between your pupils. Many opticians include your PD on the prescription; if yours does not, just ask for it. Choose your colour, pick your lens type, enter your details and add any lens upgrades. If you are unsure about size, compare the measurements above with a pair you already wear.
From our lab to you
Your Meridian Eyewear Potenza 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.
Questions we often get
Can I get varifocal lenses in the Meridian Eyewear Potenza?
Yes. The 44mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the Meridian Eyewear Potenza for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
Is it a large frame?
Yes. With 60mm lenses it suits wider faces.
What does the colour fade look like?
The colour is darker at the top of the frame and becomes lighter towards the bottom.
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.
