Hello, i like the style of these glasses, so i dont know why there is no review about them on amazon. any certification about blue blocking capacity?

Hello, have a nice day! So glad you like our glasses, the reason why there are no reviews for our glasses on Amazon is because our glasses are new releases, so it may take a while to receive customer reviews. Certification about blue light blocking capacity you can see the test report of our glasses lens blue light blocking capacity in the fifth picture.

What is the bridge size? The picture shows 15mm, but in the actual glass arm, it indicates "50-17". Would anyone can confirm?

Hello, Have a nice day, thank you for reaching out. Thank you very much for finding this mistake. This is the mistake of our technicians in the actual measurement by hand, I'm very sorry for the misunderstanding, the correct size should be the size indicated on the actual glasses arm, we have re-corrected the relevant size expression in the picture. Sincerely, LIKSMU Customer Support
