I was a little skeptical about this because I already wear blue light glasses. But I noticed an immediate difference after placing it on my phone! High quality, easy instructions, and great eye saver!
Works great . I accidentally ordered my husband the wrong size so I put his on my screen as well . I was hoping with 2 protectors at 39% effective it might double the effects lol .
The do work great So glad you love them. Two at once might be a bit darker- but the exact same spectrum of light will be blocked. Funny idea though.
The blue light blocking screen protector has been great at helping my eyesight. I've noticed I am not as fatigued towards the end of the day after being at a computer all day and can still look at my phone for simple tasks without getting a headache. Even though it is a little pricey, it's totally worth it!
