Decreased tolerance to glare is a common complaint in hydrogel contact lens wearers; yet, to our knowledge, the effect has never been quantified. By measuring increment thresholds as a function of background luminance and glare source location in two experimental conditions, while wearing a hydrogel contact lens correction and while wearing the spherical equivalent of their contact lens correction in a trial frame, we were able to quantify a significant contact lens-induced increase in glare-related visual disability. The effect is maximal at low background luminance levels, increases as the angle between the glare source and target decreases, and becomes lost in noise at high background luminance levels.
对眩光的耐受性降低是水凝胶隐形眼镜佩戴者常见的主诉;然而,据我们所知,这种影响从未被量化过。通过在两种实验条件下测量增量阈值作为背景亮度和眩光源位置的函数,一种是佩戴水凝胶隐形眼镜矫正,另一种是在试验框架中佩戴其隐形眼镜矫正的等效球镜,我们能够量化隐形眼镜引起的与眩光相关的视觉残疾的显著增加。这种影响在低背景亮度水平时最大,随着眩光源与目标之间的角度减小而增加,并在高背景亮度水平时消失在噪声中。
