About the Meridian Eyewear Collection Meridian Eyewear Diane
Meridian Eyewear Diane Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The Meridian Eyewear Diane is a unisex full-rim rectangular frame, sized 51-18-130, in Black, Brown or Red / Brown. You can order it with single vision, progressive or bifocal lenses made to your prescription. It is part of our Meridian Eyewear Collection.
3 colours to choose from
Black. Black is a deep, solid black. It looks sharp at work and just as good with jeans at the weekend.
Brown. In Brown, the frame is red-brown. It is softer than black and suits brown, auburn and red hair.
Red / Brown. Red / Brown pairs red with brown. It warms up the face and sits nicely alongside camel, olive and cream.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
The details
Rectangular lenses suit round and oval faces, adding a bit of definition.
It is the kind of frame that works with most outfits, which makes the Meridian Eyewear Diane an easy pick for everyday wear.
How to wear it
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.
Frame size and fit
| Brand | Meridian Eyewear Collection |
|---|---|
| Frame | Full Rim |
| Colours | Black, Brown, Red / Brown |
| Frame size | 51-18-130 mm (lens width, bridge, arm length) |
| Lens depth | 30 mm |
| Effective diameter | 52 mm |
The 51mm lenses make this a medium frame that suits most faces. The 18mm bridge is average. The 130mm arms are a little shorter than standard. Across the lenses and bridge it measures about 120mm.
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 Meridian Eyewear Diane
Your optometrist’s prescription will usually tell you which of these you need:
- Progressive lenses for clear vision at every distance without swapping pairs.
- Single vision for one job done well: driving, reading or desk work.
- Bifocal if you like a clearly marked reading section.
- Ready readers when you only need help close up.
The 30mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. If your prescription is on the stronger side, a thinner high-index lens keeps the edges neat, and an anti-reflective coating means fewer distracting reflections on screens and at night.
What you need to order
Have your prescription handy before you start. It will list the sphere, cylinder and axis for each eye, and often your PD as well. If your PD is missing, your optometrist can give it to you. Then simply choose your colour and lens type, enter your prescription and add any extras, such as a thinner lens or a coating. You can review everything in your cart before you pay.
How your glasses are made
Every pair is made to order. Our UK optical lab cuts your lenses to your prescription, fits them into your Meridian Eyewear Diane and then sends your glasses to you in Australia.
Looking after them
Rinse off dust before wiping, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay straight. For more tips, see our lens care guide.
Your questions, answered
Is the Meridian Eyewear Diane suitable for progressive lenses?
The 30mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Is the Meridian Eyewear Diane 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.
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.
