A glare tester was described previously and was found, in the presence of cataracts, to be almost twice as predictive as was Snellen measurement for determining visual acuity outdoors. The current study tests the reproducibility of glare test scores and the influence of refractive error and contrast sensitivity on such scores when used in a clinical environment. Although the effects of visual acuity and impaired contrast sensitivity were found to be statistically significant components of glare test scores, the magnitudes of their effects were found to be clinically insignificant. Sequential retesting of physiologically stable eyes or, in the case of progressive cataracts, within intervals short enough to preclude discernible lenticular changes indicated that, for the most part, reproducibility of glare testing was comparable to that of visual acuity testing.
先前已描述过一种眩光测试仪，发现在存在白内障的情况下，该测试仪在户外测定视力时的预测性几乎是斯内伦视力表测量的两倍。本研究测试了眩光测试分数的可重复性，以及在临床环境中使用时屈光不正和对比敏感度对此类分数的影响。尽管视力和对比敏感度受损的影响在统计学上是眩光测试分数的显著组成部分，但发现它们的影响程度在临床上并不显著。对生理稳定的眼睛进行连续重新测试，或者对于进行性白内障，在足够短的时间间隔内进行重新测试以排除可察觉的晶状体变化，结果表明，在大多数情况下，眩光测试的可重复性与视力测试相当。
