About the Brooksfield BR259
BR259 Prescription Glasses
Rectangular glasses add a little structure to the face without any fuss. The BR259 is a unisex full-rim rectangular frame, sized 51-16-140, in Black or Dark Blue. 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 Dark Blue?
Black. Black is a deep, solid black. Black suits every hair colour and frames the face with confidence.
Dark Blue. In Dark Blue, the frame is navy. It brings a cool, calm touch of colour that suits most skin tones.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Why you will like it
Rectangular lenses suit round and oval faces, adding a bit of definition.
The BR259 is a great everyday frame: smart enough for work and relaxed enough for the weekend.
Wearing it every day
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 | Brooksfield |
|---|---|
| Colours | Black, Dark Blue |
| Frame size | 51-16-140 mm (lens width, bridge, arm length) |
| Lens depth | 35 mm |
At 51mm per lens, it sits in the medium range, the most common adult fit. The 16mm bridge is on the narrow side. The 140mm arms are a standard length. Across the lenses and bridge it measures about 118mm.
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 BR259
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 35mm lens depth works with single vision, bifocal and many varifocal lenses. With a stronger prescription, a thinner high-index lens keeps the edges slim, and an anti-reflective coating cuts reflections from screens and street lights.
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.
How your glasses are made
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your BR259. Every pair is checked before it leaves us.
Keep them looking new
Clean your lenses with a microfibre cloth rather than your jumper, keep them in their case when they are in your bag, and do not leave them on a sunny car dashboard. Our lens care guide has more tips.
Questions we often get
Can I get varifocal lenses in the BR259?
Yes. The 35mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the BR259 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
What size is it?
It is size 51-16-140: 51mm 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.
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.
