Although the static behavior of accommodation in foveal vision has been well documented, the dynamic aspect of the resting state (dark focus) of accommodation is still unknown. In the present study, the accommodative dynamics of dark focus at the fovea is assessed objectively from a total of ten participants (five males and five females, aged 21–38 years) using the modified Shin-Nippon SRW-5000 autorefractor, a newly developed method to continuously monitor the accommodation process. Actual and potential applications of this study including specifications for designs are also discussed.
