About the Brooklyn D251
D251 Prescription Glasses
Upswept corners have a way of lifting the whole face. The D251 is a unisex full-rim metal cat-eye frame, sized 50-17-135, in Black, Blue, Brown or Purple. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Brooklyn range.
Choosing your D251 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 looks great with blue or grey eyes and pairs easily with denim and white.
Brown. Brown is a warm, earthy brown. It warms up the face and sits nicely alongside camel, olive and cream.
Purple. Purple is a rich purple. It works beautifully with navy, grey and silver jewellery.
If you are stuck between two, choose the one closest to the colours you wear most. You can always add a second pair later.
Design details
The upswept outer corners suit round, oval and square faces especially well, giving the face a gentle lift. Decorative arms give the frame a finished, designer feel when you see it side on.
The tortoiseshell arms pair nicely with the front and give the frame a relaxed feel. The patterned finish means no two angles look quite the same. Metal lets the frame stay slim and light while keeping its shape.
The D251 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 | Brooklyn |
|---|---|
| Colours | Black, Blue, Brown, Purple |
| Frame size | 50-17-135 mm (lens width, bridge, arm length) |
| Lens depth | 37 mm |
With 50mm lenses, this is a compact frame that suits smaller faces. The 17mm bridge is average. The 135mm arms are a standard length. Across the lenses and bridge it measures about 117mm.
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 D251
Pick the lenses that match your prescription:
- 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. 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.
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 D251. Every pair is checked before it leaves us.
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.
FAQs
Can I get varifocal lenses in the D251?
Yes. The 37mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the D251 for driving?
Yes. Single vision or varifocal lenses work well for driving, and an anti-reflective coating helps cut glare from headlights at night.
Is it a small frame?
Yes. With 50mm lenses it suits smaller faces.
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.
