PURPOSE/METHOD: To measure the photopic contrast sensitivity, with and without glare, by means of a new instrument. Seventy eight right eyes of 49 young adults and of 29 adults subjects between 35 and 55 years were studied. Contrast sensitivity was measured with the Contrast Glaretester CGT-1000 (Takagi, Japan) that determines the contrast threshold by means of an automated strategy for 6 spatial frecuencies.
RESULTS/CONCLUSIONS: The values of contrast sensitivity were similar to those obtained with other clinical tests. Contrast sensitivity, without and with glare, decreased significantly with the age. However, glare did not modify the contrast sensitivity under photopic conditions.
目的/方法：使用一种新仪器测量明视条件下有无眩光时的对比敏感度。研究了49名年轻人和29名年龄在35至55岁之间成年人的78只右眼。使用对比眩光测试仪CGT - 1000（日本高木）测量对比敏感度，该仪器通过自动策略测定6种空间频率的对比阈值。
结果/结论：对比敏感度值与其他临床测试所得结果相似。有无眩光时的对比敏感度均随年龄显著降低。然而，在明视条件下，眩光并未改变对比敏感度。
