Does the Blue Sky setting on Flux actually reduce blue light?



  • Hello,
    I got flux and really like using the Blue Sky setting because it is relaxing to they eyes and doesn't obscure color to much. But I wondering if this actually helps to reduce the emission of the harmful blue light to our eyes. Does anyone know if it does? Thank you

    I wouldn't use it all night long, but during the day, it's likely pretty safe to use.
