STARS is an AI-powered smart system for the early detection and simplified monitoring of myopia, lazy eye risks and strabismus for children. Unlike traditional examinations that require professional training and the use of bulky and expensive instruments, STARS offers a compact, user-friendly solution, with AI-assisted photo-refraction that ensures precision and user comfort. Its multi-lingual interface makes vision screenings accessible and easy, especially benefitting those in remote and developing regions. 

Developed and patented by PolyU, the AI algorithms in STARS are continuously optimised using large data sets. It was built on more than 30,000 real-life clinical eye profiles, enabling STARS to quickly provide reliable and reproducible results. With deep learning, the technology will become increasingly precise over time.
