Blue light filter dkt phone mmg takda effect. Lagi2 iPhone.
Your blue blocking glasses need to be orange. Bukan yg clear lenses byk2 jual kat kedai, that’s a scam and & that’s why u got mad.
To know if your blue light filter is effective or not test with this photo.

With the correct blue light filter you should not be able to see the “B” colour.
Spectra479 blocks the “B” colour till you can only see a faded round shape. That’s the best we get so far for its price.
