About the EMP7581
EMP7581 Prescription Glasses
Rectangular frames are the dependable all-rounders of eyewear. The EMP7581 is a unisex full-rim rectangular frame, sized 51-17-135, in Blue or Crystal Pink. You can order it with single vision, varifocal or bifocal lenses made to your prescription.
Choosing your EMP7581 colour
Blue. Blue is a clear, easy-to-wear blue. It brings a cool, calm touch of colour that suits most skin tones.
Crystal Pink. Crystal Pink is easy to wear. It blends in rather than stands out, which many people find easy to wear every day.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
About the EMP7581 design
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 EMP7581 is a strong choice.
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
| Colours | Blue, Crystal Pink |
|---|---|
| Frame size | 51-17-135 mm (lens width, bridge, arm length) |
| Lens depth | 34 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 17mm bridge is average. The 135mm arms are a standard length. Across the lenses and bridge it measures about 119mm.
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 EMP7581
Choose the lens type that suits how you use your glasses:
- 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.
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.
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.
How your glasses are made
Your EMP7581 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.
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.
FAQs
Is the EMP7581 suitable for varifocals?
The 34mm lens depth is fairly shallow, so single vision or bifocal lenses usually work better.
Can I wear the EMP7581 for driving?
Yes. Single vision lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 51-17-135: 51mm lens width, 17mm 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.
Who glazes my lenses?
Our own optical lab in the UK. Your lenses are made to your prescription and fitted into the frame before your glasses are sent to you.
