Abstract
Stationary sinusoidal gratings red, green and blue (40 cd/m2) were presented to eight subjects using a psychophysical adjustment technique to establish sensitivity functions; 1 — in foveal vision; 2 — in peripheral vision: 10°, 20°, 30°, 40°, nasal retina on the horizontal meridian.
Result quantification indicates: 1 — that there is no difference among colours in foveal vision; 2 — that perception is greatly and equally reduced for all colours in peripheral vision; 3 — that this phenomenon depends on spatial frequencies.
The least deteriorated frequencies are medium range spatial frequencies (1 cycle/deg.). This method is the basis of the studies presently conducted to quantify decreases in visual function.
