About the Brooklyn D270
D270 Prescription Glasses
If you want glasses that look smart and get out of the way, a rectangle is hard to beat. The D270 is a unisex full-rim metal rectangular frame, sized 53-18-140, in Black or Blue. You can order it with single vision, varifocal or bifocal lenses made to your prescription. You will find it in our Brooklyn collection.
Choosing your D270 colour
Black. Black is a deep, solid black. It is the safest choice if you only want one pair, and it never looks out of place.
Blue. Blue is a clear, easy-to-wear blue. It is a fresh alternative to black that still looks professional.
Each colour is shown in the gallery, so you can compare them side by side before you decide.
Design details
Rectangular lenses suit round and oval faces, adding a bit of definition. Being semi-rimless, it keeps a defined top line while the lower half of the lens stays open and light.
The slim metal construction keeps it light and neat, and it is easy for an optician to adjust.
It is the kind of frame that works with most outfits, which makes the D270 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.
Size and fit
| Brand | Brooklyn |
|---|---|
| Colours | Black, Blue |
| Frame size | 53-18-140 mm (lens width, bridge, arm length) |
| Lens depth | 36 mm |
At 53mm per lens, it sits in the medium range, the most common adult fit. The 18mm bridge is average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 124mm.
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 D270
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 36mm 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.
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.
Made for you in our UK lab
Every pair is made to order in our own UK lab. Your lenses are cut to your prescription, fitted into your D270 and checked by our technicians before they are sent out.
Keep them looking new
Use lens spray and a soft cloth, fold the arms before putting your glasses down, and store them in a hard case. Our guide to looking after your lenses covers the rest.
Questions we often get
Can I get varifocal lenses in the D270?
Yes. The 36mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the D270 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 53-18-140: 53mm lens width, 18mm bridge and 140mm arms, a medium fit.
What does semi-rimless mean?
The frame runs along the top of the lenses only. The lower edge is held by a fine line, so the bottom of the lens is open.
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.
