Review on 👓 Prevent Eye Strain & Fatigue with Blue Light Blocking Glasses - UV Filter Lenses, Non-Prescription - Ideal for Work, Gaming, Reading - for Men & Women - Matte Black, One Size by Billy Braggs

The 'blue light' card that came with the glasses is a scam. Please find her. It turns purple with UV rather than blue light. Glass that transmits visible light absorbs almost all of the ultraviolet light. After this purchase I bought true blue light glasses and with them you cannot see blue light and most blue tones that are not light appear significantly darker. A friend's blue gaming chair looked gray. However, I can confirm that there appears to be some blue light filtering, but I can assure you that you won't feel any significant effects. Whatever you are feeling is most likely a placebo. Not to mention they sent me the wrong color. I'm only giving this three stars because the customer service was exemplary.
