Still have questions?

We answer the most common questions. If you need anything else, our opticians are happy to help.

Talk to an optician

Yes. After configuring your lenses we send you a prepaid envelope to send us your frame. Our opticians check it, fit the new lenses and return it ready.

It usually takes 5 to 10 working days from when we receive your glasses, depending on the lens type and chosen treatments.

Of course. We offer progressives from various ranges and labs. In the configurator you choose the quality and we handle the precise assembly.

No problem. We offer high-index lenses (1.60, 1.67, 1.74) that thin down the lens to make it lighter and more attractive, even for strong prescriptions.

Yes. You can fit sun lenses with or without prescription, in different colours, gradients, polarised or photochromic, keeping your favourite sunglasses frame.

Your latest optical prescription is enough. If in doubt, our team of opticians will advise you with no obligation before you order.

Anti-reflective, hardened, blue-light filter, photochromic, polarised and thickness reduction, among others. You can combine them depending on how you'll use your glasses.
