The use of screen devices, such as cell phones, tablets, and computers, is associated with increased risk of myopia progression in children. This project aims to develop eye-safe electronic displays that reduce the risk and progression of myopia in children by counteracting harmful visual signals generated by digital screens. Building on proven optical principles used in anti-myopia lenses, the study develops novel screen-based technologies that induce myopic blur during screen use. The work focuses on creating software-based solutions, including simulated myopic defocus enabled by eye tracking and real-time image processing, which can be applied flexibly across different digital devices and activated as needed to provide therapeutic visual effects.
