What to know before buying

Listing details to confirm

The listing claims 90% blocking of harmful blue light from digital devices, while separately claiming 100% UV-ray blocking. These are distinct claims, not a single combined protection figure, and neither is independently verified here. The light-yellow tint may affect colour perception despite the listing's low-distortion claim. Confirm lens suitability and prescription replacement details with an optical shop if these matter to you.

Who is it for?

A good fit for

Adults seeking square-frame glasses marketed for screen use.
Buyers who want lightly yellow-tinted lenses and may seek prescription-lens replacement through a local optical shop.
