About the EMP7591
EMP7591 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The EMP7591 is a unisex full-rim rectangular frame, sized 51-18-135, in Matt Purple. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Rimless range.
The colour
Matt Purple. Matt Purple is easy to wear. It adds a confident touch of colour and suits fair and cool skin tones.
The details
Rectangular lenses suit round and oval faces, adding a bit of definition. With no rim around the lenses, the frame almost disappears on the face.
If you want a frame you can put on in the morning and forget about, the EMP7591 is a strong choice.
Styling tips
Choose the colour closest to what you wear most and it will go with almost everything.
Frame size and fit
| Colours | Matt Purple |
|---|---|
| Frame size | 51-18-135 mm (lens width, bridge, arm length) |
| Lens depth | 34 mm |
The 51mm lenses make this a medium frame that suits most faces. The 18mm bridge is average. The 135mm arms are a standard length. 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 EMP7591
Pick the lenses that match your prescription:
- 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 34mm lens depth is on the slim side, so single vision or bifocal lenses usually work best. 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
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your EMP7591. Every pair is checked before it leaves us.
Looking after them
Rinse off any grit before you wipe, dry the lenses with a clean microfibre cloth, and take your glasses off with both hands so the arms stay aligned. See our lens care guide for more.
A second pair?
Plenty of people keep more than one pair of glasses: one for work, one for home, or a spare in the car. A second pair also means you are never stuck if your main glasses are being repaired. This frame is an easy choice for either role.
Your questions, answered
Is the EMP7591 suitable for varifocals?
The 34mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Is the EMP7591 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 51-18-135: 51mm lens width, 18mm bridge and 135mm arms, a medium fit.
What does rimless mean?
There is no frame around the lenses. They are held by the bridge and arms only, which makes the glasses very light.
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.
