## Before you buy

- 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.

## 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.

## Less suited to

- Buyers who require clear, untinted lenses or independently verified lens-performance figures.

## Customer feedback

The supplied evidence includes only aggregate ratings, with a small sample and all ratings in the five-star category. That is a positive but limited signal and does not identify what buyers liked or establish lens performance, fit or durability.

## Frequently asked questions
