Abstract: The wearing comfort of augmented reality (AR) glasses is of great importance to achieve prolonged and immersive experience. This study proposed an evaluation method for long-term wearing comfort of AR glasses. A frame prototype that can adjust the frame width smoothly was designed in this study. The effects of physical loads (30g, 45g, 60g, 75g) and clamping forces (0.3N, 0.6N, 0.9,N 1.2N, 1.5N) on subjective discomfort were also investigated. The results show a linear relationship between subjective discomfort, added physical load and increasing clamping force within an hour. It was found that the inflection point of subjective discomfort occurred when the physical load on the nose was 60g and the clamping force on the headside was 1.2N.
