Abstract Purpose : This study sought to find ways to improve awareness and ethics of opticians' code of ethics. Methods : A survey was conducted on 102 Korean opticians to investigate the awareness and performance satisfaction of the optician's code of ethics, as well as differences according to gender, age, education level, work experience, and workplace. Results : This study found no gender-based differences in opticians’ awareness and satisfaction with the code of ethics. However, age and education significantly influenced these factors, with higher levels observed among opticians in their 20s and 30s, particularly those in the early stages of their careers. Furthermore, a positive correlation was noted between education level and both awareness and satisfaction. The study revealed that opticians with volunteer experience exhibited higher awareness and satisfaction with the code of ethics than those without. This suggests that volunteering, which fosters professional identity and social responsibility, influences opticians’ ethical awareness. Additionally, groups with a strong interest in foreign languages and self-development demonstrated higher ethical awareness and satisfaction. Conclusion : This study underscores the need for enhanced ethical awareness among opticians. It advocates for the development of methods, case studies, and guidelines to address ethical issues not covered by the existing code, thereby revitalizing ethical practices in the profession. In addition, it is judged that active promotion and education on the code of ethics and professional ethics are necessary for the continuing education of opticians.
