[A new device for measuring contrast sensitivity with and without glare].
OBJECTIVE
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.


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.
