摘要:
Device to determine contrast sensitivity of an individual's eye, comprising means for producing real time digital images corresponding to modulated visual stimuli and display means (D) for presenting these images to the eye, and corresponding method using said device. The device performs a series of tests in a measurement session, so that the stimuli of said tests are modulated around an average stimulus in any direction of the color space and they can be configured for each measurement session. Said stimuli are usually chosen in the cardinal directions of the color space and respond to a sinusoidal grid pattern with spatial and temporal modulation, and with two dimensional gaussian envelope.
