Accommodative microfluctuations are classified into the high frequency component (HFC), 1.02.3Hz, and the low frequency component, less than 0.6Hz. HFC is considered a standard indicator of visual fatigue. We investigated the relation between HFC and pupil diameter. Results showed that HFC was high when pupil diameter was small, suggesting that pupil diameter affects HFC as an accessory function of accommodation.
