About the Brooklyn D294
D294 Prescription Glasses
If you want glasses that look smart and get out of the way, a rectangle is hard to beat. The D294 is a unisex full-rim rectangular frame, sized 57-18-148, in Black, Crystal or Grey. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It is part of our Brooklyn collection.
Which colour is you?
Black. Black is a deep, solid black. It looks sharp at work and just as good with jeans at the weekend.
Crystal. The Crystal version is crystal clear. It blends in rather than stands out, which many people find easy to wear every day.
Grey. In Grey, the frame is black and grey. It is a great match for cooler skin tones and a crisp, tidy look.
Still torn? Think about what you wear on an ordinary weekday, not on a night out. That is the colour you will be happiest with.
Design details
Rectangular lenses suit round and oval faces, adding a bit of definition. A crystal front looks modern and light, and it goes with everything.
If you want a frame you can put on in the morning and forget about, the D294 is a strong choice.
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 | Brooklyn |
|---|---|
| Colours | Black, Crystal, Grey |
| Frame size | 57-18-148 mm (lens width, bridge, arm length) |
| Lens depth | 37 mm |
At 57mm per lens, it is a generous size, a good pick if standard frames feel tight. The 18mm bridge is average. The 148mm arms are on the longer side, which suits larger heads. Across the lenses and bridge it measures about 132mm.
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 D294
Choose the lens type that suits how you use your glasses:
- Varifocals if you want to see near and far without swapping glasses.
- Single vision for one task done well, such as driving, reading or screen work.
- Bifocals if you prefer a clearly defined reading area.
- Ready readers for straightforward close-up help.
The 37mm 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.
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.
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 D294 and checked by our technicians before they are sent out.
A little care goes a long way
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 D294?
Yes. The 37mm lens depth gives varifocal lenses enough height for all three vision zones.
Is the D294 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.
Is it a large frame?
Yes. With 57mm lenses it suits wider faces.
What does crystal mean?
A clear, see-through finish.
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.
