  Beijing, July 13 (Reporter Yang Zhaokui) Recently, affected by the epidemic, many large, middle and primary schools continue to use online methods for teaching. Because online teaching requires children to use mobile phones, computers and other electronic products for a long time, it has a greater burden on children's vision. Some businesses have begun to speculate on the blue light hazards of electronic products, and promote and promote anti-blue light glasses that can "prevent myopia and protect eyesight."

For some businesses, through false exaggeration of the performance of anti-blue light products, excessive interpretation of the hazards of blue light, and high-priced sales of anti-blue light products, it should be treated rationally.
