Subretinal prosthesis can utilize more retinal live cells to process visual signal and has attracted most attention in the field of artificial visual function recovery.

A new visual function recovery circuit,which generates electrical pulses with frequency proportional to the intensity of incident light,is proposed.

Electrical characterization of flexible neural microelectrode array for retinal prosthesis;

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.

The functional recovery of the completely transected spinal cord rat was promoted by combinative grafting neural stem cells and NT-3 genetically modified Schwann cells;
