About the Brooklyn D139
D139 Prescription Glasses
A round frame is an easy way to add a little character. The D139 is a unisex full-rim round frame, sized 51-19-140, in Crystal Grey or Crystal. You can order it with single vision, varifocal or bifocal lenses made to your prescription. It belongs to the Brooklyn range.
Crystal Grey or Crystal: which one is you?
Crystal Grey. Crystal Grey keeps things simple. It keeps the look soft and understated, and it works especially well on fair skin.
Crystal. In Crystal, the frame is crystal grey. Because light passes through it, the frame looks lighter on the face and lets your features do the talking.
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.
About the D139 design
Round frames soften angular features, so they are a great match for square and heart-shaped faces. The crystal finish is clear and fresh, and it lets your features take centre stage.
It is the kind of frame that works with most outfits, which makes the D139 an easy pick for everyday wear.
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.
How it fits
| Brand | Brooklyn |
|---|---|
| Colours | Crystal Grey, Crystal |
| Frame size | 51-19-140 mm (lens width, bridge, arm length) |
| Lens depth | 44 mm |
The 51mm lenses make this a medium frame that suits most faces. The 19mm bridge is a little wider than average. The 140mm arms are a standard length. Across the lenses and bridge it measures about 121mm.
To check the fit, look at the three numbers printed inside the arm of glasses you already own. If they are within two or three millimetres, this frame should feel similar.
Lens options for the D139
Your optician’s prescription will usually tell you which of these you need:
- 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.
At 44mm, the lens depth is deeper than most frames in our range, so varifocal lenses have lots of room. 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.
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.
From our lab to you
Pick your colour and lenses, add your prescription and PD, and our UK lab cuts your lenses and fits them into your D139. Every pair is checked before it leaves us.
Looking after them
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.
Your questions, answered
Can I get varifocal lenses in the D139?
Yes. The 44mm lens depth gives varifocal lenses enough height for all three vision zones.
Can I wear the D139 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 51-19-140: 51mm lens width, 19mm bridge and 140mm arms, a medium fit.
What does crystal mean?
A clear, see-through finish.
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.
