An experimental study and mathematical analysis of the corneal reflex test was undertaken in spectacle wearers. In the experimental study, photographs were taken of the corneal reflex through spectacles and the conversion ratios determined as measured in degrees/mm. In the mathematical analysis, the magnification effect of the lens was elucidated by three methods: geometrical analysis; real measurement of magnification factor; and ray tracing analysis. The real measurement of the conversion ratios was in good agreement with the conversion ratios determined by the three mathematical analyses. These results clearly showed that the corneal reflex test can be clinically useful even in wearers of spectacles.
对佩戴眼镜者进行了角膜反射试验的实验研究和数学分析。在实验研究中，透过眼镜拍摄角膜反射的照片，并确定以度/毫米为单位测量的转换率。在数学分析中，通过三种方法阐明了镜片的放大效果：几何分析；放大倍数的实际测量；以及光线追踪分析。转换率的实际测量结果与三种数学分析确定的转换率高度一致。这些结果清楚地表明，即使对于佩戴眼镜的人，角膜反射试验在临床上也是有用的。
