These blue light countermeasure glasses cut out the "blue light" produced by displaying smartphones, tablets, game consoles, and keep children's eyes. Cuts blue light by about 50% and reduces the amount of blue light reaching the retina. We put the safety of your children first, using lenses that are impact resistant and not easy to break, and the nose pad is designed to be integrated into the frame. Ultra lightweight elastic material "TR-90" has been adopted in the temples (the part that supports the glasses and face), so it is difficult to hurt your ears. Comes with a storage pouch for easy carrying and storage. The pouch can be used as a cleaning cloth.
