Search time was tested as a index for evaluating visual performance of color coding for characters and parametric effects of foreground color, background color, character size and illuminant condition on the visual performance in synthesized information displays.

Deliberation as to the damnific degree classification of visual function in the Classification Standard of Accidents in Medical Treatment;

Objective To study the locomotive drivers' visual function status and analysis the requirements and changes of high-speed train.

Visual function accounted for the variance.

The advancement of researches on dyslexia and vision function;

Most of sports require comprehensive vision function,which include not only sharp visual acuity,stereo,color and visual field but also dynamic ocular movements,accommodation and convergence,etc.

The characteristics and optimized design of tunnel lighting are analyzed in this paper based on people s visual performance and some international standard.

This research is to find out the effects of light level, visual angle and eccentricity on the spectral sensitivity of human eyes at mesopic region; to validate the possibility of working out the spectral luminous efficacy curves based on visual performance at mesopic light levels; to find the connection between the results of performance-based method and brightness-matching method.
