Key Evaluation Techniques and Criteria of Visual Health in Virtual Reality

Study Overview
=================
Brief Summary
-----------------
China's VR industry is booming, but it also faces many problems. At present, industry standards for key physical parameters of virtual reality are still being explored. More and more attention has been paid to the visual health and safety of VR. Based on ophthalmology-neurologic technology, this study screened VR ocular safety parameters, constructed VR evaluation model and provided visual health evaluation system and standards for VR technology.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Accommodative Response | The actual amount of accommodation that exists is measured with a skiascope | 60 min | 
| AC/A Ratio | The ratio of accommodation convergence to accommodation is measured and calculated by maddox | 60 min |
