About the Brooksfield BR258
BR258 Prescription Glasses
If you want glasses that look smart and get out of the way, a rectangle is hard to beat. The BR258 is a unisex full-rim rectangular frame, sized 54-16-140, in Black or Black/Brown. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Brooksfield collection.
Black or Black/Brown?
Black. Black is a deep, solid black. It defines the eyes and goes with every outfit you own.
Black/Brown. Black/Brown mixes black and brown. It looks sharp at work and just as good with jeans at the weekend.
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.
If you want a frame you can put on in the morning and forget about, the BR258 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.
Size and fit
| Brand | Brooksfield |
|---|---|
| Colours | Black, Black/Brown |
| Frame size | 54-16-140 mm (lens width, bridge, arm length) |
| Lens depth | 35 mm |
The 54mm lenses put it at the upper end of medium. The 16mm bridge is on the narrow side. The 140mm arms are a standard length. Across the lenses and bridge it measures about 124mm.
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 BR258
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.
The 35mm lens depth works with single vision, bifocal and many varifocal lenses. 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.
Made for you in our UK lab
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your BR258. Every pair is checked before it leaves us.
A little care goes a long way
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.
Questions we often get
Can I get varifocal lenses in the BR258?
Yes. The 35mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I use the BR258 as computer glasses?
Yes. Single vision lenses set to your screen distance, or varifocals if you also need distance vision, both work well for desk work.
What size is it?
It is size 54-16-140: 54mm lens width, 16mm bridge and 140mm arms, a medium fit.
Will it suit a narrow nose?
Yes. The 16mm bridge is designed for slimmer noses.
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.
