Glare disability and contrast sensitivity loss can be present in cataract patients with minimally reduced visual acuity. Objective and subjective visual function was analyzed in 72 patients (mean visual acuity = 20/40) before and after cataract surgery. Following surgery, most subjects regained normal function in all tests. Improvement in contrast sensitivity and reduction of glare disability were independent of preoperative visual acuity. Subjective improvement in visual function was predicted by acuity and contrast sensitivity tests.
轻度视力下降的白内障患者可能会出现眩光障碍和对比敏感度损失。对72例患者（平均视力=20/40）在白内障手术前后的客观和主观视觉功能进行了分析。手术后，大多数受试者在所有测试中都恢复了正常功能。对比敏感度的改善和眩光障碍的减轻与术前视力无关。视力和对比敏感度测试可预测视觉功能的主观改善。
