In recent years, with the continuous improvement of computer science and technology, artificial intelligence(AI)technology based on deep learning(DL)has developed rapidly and attracted wide attention all over the world. Great progress has been made in the research and application of AI in the medical field. In the field of optometry, AI can assist the diagnosis of myopia, strabismus, amblyopia and other diseases, and has achieved good results in the screening and early diagnosis of keratoconus as well as in the prevention and correction of myopia. Nevertheless, there are some limitations and great challenges in the application of AI in optometry, including clinical and technical challenges, interpretability of algorithmic results, medical legal issues and so on. This paper reviews the application, limitation and prospect of AI in the field of optometry.
