The effect of applying modular teaching mode in the practice teaching of optometry technology majors was studied. This paper compared the comprehensive evaluation results of professional theory and quality and skills of interns who adopted traditional teaching methods (control group) and modular teaching mode (experimental group) after their internship, and conducted an anonymous questionnaire survey on the students of the two groups. The results showed that the comprehensive evaluation results of the experimental group were significantly higher than those of the control group (P<0.05), and the internship satisfaction of the experimental group was also significantly higher than that of the control group (P<0.05). The results also showed that modular teaching had shown high efficiency and practical advantages in the teaching of optometry technology major, helping to master the core knowledge and skills required for the post of optometry, and improving the students' satisfaction with their teaching staff.
