The Dark Focus of Visual Accommodation: Its Existence, Its Effects, Its Measurement
The "dark focus" or "resting state" of visual accommodation to the refractive state to which the eye tends to return in the absence of any visual stimulus, as in complete darkness. This tendency is reviewed in terms of past and current attempts at its quantification and its effects on visual …

The Effect of Age on Dark Focus Distance and Visual Information Transfer Rate
… the dynamic aspect of the resting state (dark focus) of accommodation is still unknown. Previous studies suggest that refractive error is minimal at the intermediate resting point of accommodation — i.e., at the dark focus distances. Additionally, aging is closely linked to increased …

User-centered Virtual Environment Assessment And Design For Cognitive Rehabilitation Applications
… point to user characteristics (e.g., changes in dark focus) that may introduce error in the evaluation of VE based rehabilitation protocols. Based on these results, we provide guidelines for calibrating and benchmarking HMDs. In addition, we discuss potential extensions of the assessment to …
