Research

Every claim, with the source

We do not claim that blue light glasses reduce eye strain. Large review studies have found insufficient evidence for this. Therefore, we do not make such promises. We only tell you what research does show. Being honest is more important than making a sale.

What we deliberately do not claim

We do not claim that blue light glasses reduce eye strain. Large review studies find insufficient evidence for this. Therefore, we do not promise it. Being honest is more important than a sale.
