简要总结
The aim of this study is to test whether it is possible in principle to determine defective vision using light field technology. The measurements with this first prototype will be compared with the results of the conventional method for subjective refraction determination and those using a phoropter (Vision R-800 phoropter).

结局指标
主要结局
precision of determination of refractive error
时间窗: within one week
To explore if this prototype CREAL device based on LightField Technology can determine the refractive error reliably, in comparison to well-established methods such as subjective refraction with a trial frame and with the phoropter Vision-R 800 (Essilor SA).
次要结局
- repeatability of all three methods for subjective refraction(within one week)
