A method is presented for quantitative measurements of the glare effect of light scattered in the ocular media. The contrast sensitivity function is measured with a television display system. A bright light source is introduced into the field of vision, and the resultant decrease in contrast sensitivity is mea-ured. It is further used to calculate a scattering factor which is a direct measure of the intraocular light scattering. The scattering factor shows a marked increase in patients with early cataracts even if their visual acuity is not affected.
本文介绍了一种定量测量眼内介质中散射光眩光效应的方法。使用电视显示系统测量对比敏感度函数。将一个明亮光源引入视野，并测量由此导致的对比敏感度下降。进一步用它来计算一个散射因子，该因子是眼内光散射的直接度量。即使早期白内障患者的视力未受影响，其散射因子也会显著增加。
