两项调查询问了健康成年人的日常视力问题。参与者的年龄从 18 岁到 100 岁不等，并接受了严重视力障碍的筛查。受访者评价了他们执行视觉任务时遇到的困难频率，例如阅读、识别物体、在人群中辨认出一张脸、在昏暗的环境中看东西、看到移动的物体等等。调查显示，五个维度随着年龄的增长而下降：视觉处理速度、光敏感性、动态视觉、近视力和视觉搜索。报告这些视觉维度下降的受访者百分比在整个成年寿命中增加了两到六倍。不同任务的视力下降速度不同，表明视力各个方面的老化速度不同。
A pair of surveys asked healthy adults about their everyday visual problems. Participants ranged in age from 18 to 100 and were screened for major visual impairment. Respondents rated the frequency of difficulty they had performing visual tasks such as reading, recognizing objects, picking out a face in a crowd, seeing in dimly lit environments, seeing moving objects, and so on. The surveys revealed five dimensions that declined with increasing age: visual processing speed, light sensitivity, dynamic vision, near vision, and visual search. The percentage of responents reporting a decline in thse visual dimensions increased two- to six-fold across the adult life span. Varying rates of visual decline for different tasks suggest that various aspects of vision age at different rates.
