Man perceive and react around him through the five senses. Also man give rise to the human sensibility and maintain his emotion. This study doesn't limit working environment to VDT environment, but considers the universal working environment acquiring information by eyesight stimulation. In this respect, designed and made is experimental equipment such as an external light for veiling reflection, visual target suggesting system, and visual target considered luminance contrast level. And reading the visual target is selected as work after excerpting the editorials from daily newspapers in Korean and Chinese letter and making target for experimental condition. In case of forming an abnormal veiling reflection we consider the form; a vertical (25%, 50%, 75%)and a horizontal (25%, 50%, 75%). The results from the subjective evaluation are analyzed by SD (Semantic Differential) methodology of 5 point scale for visibility and nuisance when an abnormal veiling reflection forms on target. In addition, the results of the objective evaluation are suggested by measuring and analyzing EEG (Electroencephalogram) of bio-signal for visual sensitivity. The results of this study can apply to basic data which create a guideline of a visual operation. In particular, it can be designed as an illumination environment concerning an ergonomic factor on visual operations, mental stress such as a visual inspection operation, visual information search operation, etc. As a result, we can expect to reduce the visual nuisance and contribute to the improvement of the performance and the uplift of the competitive power.
