实验用‘干净’的发散激光光束照射非反射性的表面,产生激光斑纹。依据斑纹的运动与人眼屈光状态的关系,采用H·A·Knoll和W·N·Mohon等人介绍的方法,可以检查和矫正人眼屈光不正。分析结果表明:激光斑纹验光法简易、快速、准确,是一种很有发展前途的主观验光方法。
Experiments use a ’clean’ divergent laser beam to illuminate the non-reflective surface and produce laser mottle. Based on the relationship between the motility of the streaked eye and the refractive status of the human eye, the methods described by H · A · Knoll and W · N · Mohon et al. Can be used to examine and correct refractive errors in the human eye. The analysis results show that laser speckle refraction method is a simple, rapid and accurate method, which is a promising subjective refraction method.
