[Energy characteristics of vision with the use of electronic displays].
When developing diagnostic apparatuses to assess visual power characteristics by means of electronic displays, much attention should be paid to metrological aspects. To meet the metrological requirements for sensitivity, measurement range and errors, etc. allows one to detect the changes concerned in visual characteristics and visual disorders at different stages of pathological development. To estimate visual frequency-contrast sensitivity and colour discrimination ability, the number of reproduced brightness gradations for each display primary colour R, G or B should be at least 256 and the discrete raster format of test image, 512 x 512 elements. Recommendations are given on display operation modes with the aim of enhancing the accuracy of estimating visual characteristics.
