Review on 👓 Protective Eye Care: Gaoye 2 Pack Blue Light Blocking Glasses for Kids, Ages 3-12 – Shield from Computer Gaming and UV Rays by Ameer Kobblewood

Works well. It blocks most of the blue light when I used their little UV light tester and card. I'd say it's 90-95% blocked. And my daughter loves wearing it. FYI: I used the same light and card and placed my transitional prescription glasses between the light and card. it was 100% UV blocking. Using this as my comparison, I'm pretty sure that 90-95% of the right glasses will fit these blue sun goggles for kids. And for the price it's great!
