Do my new glasses have any kind of warranty?

Yes, we offer a two-year warranty on the frame and on manufacturing defects of the

ophthalmic crystals.

The warranty does not cover breakages or damages made voluntarily or involuntarily by the user.

In case of manufacturing defect, please contact us and we will pick up your glasses in order to change them. We’ll send them back to you with the new lenses and/or the new frame.

If we do not have the very same model you bought, you can choose from the existing collection at the time of the change.

What type of frames and lenses do you work with?

All our products meet the highest quality requirements.

Frames: we use the most resistant materials on the market: titanium, Italian ultem, steel and premium acetate.

Lenses: we rely on a Spanish optical laboratory with more than 50 years of experience in the sector: Prats Laboratories.

Our prescription GreyGlasses include:
  • High ( or super high-index), organic CR39 lenses, with scratch-resistant coating.
  • Anti-reflective coating that reduces annoying reflections and reduce eye strain.
  • Protective cover.
  • Cleaning cloth.
  • Mini screwdriver, to adjust your glasses yourself in case you can’t go to the optics.


Home Try-On: How does it work?

You can choose up to 5 frames you like the most from our website and we will send them to you for free wherever you want.

You can keep the glasses for 3 full days, and ask your friends and relatives for advice!

Once you have decided the frame that suits you best, please call or write to us so we can pick up the trial frames (in the same box we sent you).

If you have already found your match, order your glasses online and we’ll get started on delivering your brand new glasses asap!

Home Try-On: Is it free of charge?

Yes, our 3-days Home Try-On service is completely free of charge. 

During the pick up process, we will ask for your bank details to secure the order with a credit or debit card. No worries, we will only retain €1 as a deposit that we will return after receiving the glasses back.

At the moment our Home Try-On is available in Spain (except for the Balearic Islands, the Canary Islands) and Portugal.

Our Home Try-On is valid only for prescription glasses and screen glasses.

What happens if I don't return or break any of the trial frames?

In the case of non-return of the frames or if any of them is damaged, we’ll proceed charging to the account you gave us of up to €84 for each frame not returned or damaged.

To avoid the charge, please deliver to the courier the trial frames in their box.

Don’t worry, once the 3 days have passed, we will contact you to plan the pickup.

If your trial period ends on weekend or on vacation, a new pickup will be scheduled for the next working day.

If I liked one or more frames, can I order them online?

That’s easy! Go to and finish the order online by choosing the frames you liked the most. We will need your prescription details and delivery address.

You don't have to wait for the pickup of the trial frames to finish your online order.

What if I finally don't like any of the frames?

Don't worry, you don't have any commitment to purchase. 

If you do not find your perfect model, just return the trial frames and we will refund your deposit.

We are sure you’ll find your perfect GreyGlasses in our next collection!
