Bflex B-Original BF040155 Men’s Unbreakable Square Eyeglasses – Satin Black/Blue, 55mm

Sit on them, drop them, pack them in a gym bag: the Bflex B-Original BF040155 is an unbreakable men’s square frame in satin black/blue, made to keep up with an active day. It features a keyhole bridge, bevelled detailing along the top and Siliflex temples with contrasting texture. Satin black with blue accents reads classic from the front and sporty from the side.

Bflex is a Spanish eyewear brand of unbreakable prescription glasses for active adults. Frames are made from patented Siliflex™, a lightweight, super-flexible material that is BPA-free and 100% recyclable, and lighter than acetate. The Hinge 3.0 lets the temples rotate up to 360°, adjustable temple tips keep the fit secure, and a magnetic front accepts the Bflex clip-ons. Every frame comes with a Bflex cord.

Built for an active life

• Cord included: a rubber-coated steel cord with silicone stoppers comes in the box, so your glasses hang safely around your neck instead of falling off.
• Solar Clip (AED 160, optional): a magnetic sun clip with polarized category 3 lenses and BlueBlock™ treatment — it snaps onto the front and turns your prescription glasses into sunglasses for daytime driving, the beach or outdoor training.
• Night Driving Clip (AED 160, optional): a yellow-tinted magnetic clip (category 1, BlueBlock™) that improves contrast in low light and at night.
• Sports headband (AED 75, optional): an elastic band that replaces the standard temples for jogging, the gym or active work, so the glasses stay firmly in place.

Frequently asked questions

Are Bflex glasses really unbreakable?
Bflex frames are made from Siliflex™, a patented flexible material that bends and returns to its shape, and the Hinge 3.0 lets the temples rotate up to 360° instead of snapping at the hinge. That makes the B-Original far more resistant to sitting, dropping and twisting than an ordinary acetate or metal frame. Lenses can still scratch, so use a case when you can.

Can I wear these glasses for running or sport?
Yes — add the Bflex sports headband (AED 75), which replaces the standard temples and keeps the glasses secure while jogging, training or doing active work, and choose impact-resistant lenses. Bflex frames are everyday prescription glasses, not certified safety or protective eyewear.

Can I turn these into prescription sunglasses?
Yes. Add the magnetic Bflex Solar Clip (AED 160, polarized category 3) and it snaps onto the front over your prescription lenses. For night driving, the yellow Night Driving Clip (AED 160) improves contrast in low light.

Do you deliver to Dubai?
Yes — free delivery across Dubai and all UAE. Home try-on is available in Dubai and Abu Dhabi, and you can visit our Abu Dhabi store for fitting.
