BOE's Longview screen (Eaglet Standard Edition), priced at 12,000 yuan, boasts of preventing myopia. However, numerous parents have reported that their children's eye axes have grown rapidly, accompanied by eye pain and tearing after using the device. Despite customer service's assertion that increased usage leads to better results and that the eye axis regresses upon discontinuation, these claims have sparked significant skepticism. Doctors emphasize that the prevention and control of myopia necessitate scientific eye use and outdoor activities, while the efficacy of high-priced equipment like this is limited.
