87% of parents have no idea what screen time does to their children.
Are you one of them?
Blue Light Blockers have UV400 lenses with blue light coating that block ~70% of all blue light (and most of the harmful blue light spectrum) and perfectly fit ages 3-12.
The blue light test light is directly irradiated on the anti-blue light test card and presents a purple-brown color. If the blue light test light is passed through the anti-blue light test card illuminated by the anti-blue light glasses, there is no purple brown, indicating that the blue light is effectively blocked.
UV Protection Test
Without the blocking of UV-protecting glasses, the sensor's sensing digital display is 0, indicating no interference. If the detector displays the corresponding value under the protection of the UV-protecting glasses, it effectively blocks the UV.
