Outline of Final Research Achievements	We studied whether ight color affected the intraocular scattering light on fovea. The luminance difference threshold is measured for calculating the adaptation luminance increase as intraocular scattering light. The variables of this experimental are luminance of the near-background, size of the visual target, their colour and the colour of glare source. The colour conditions are blue, green, yellow, red and white. The subjects were 17 young female. Their ages ranged from 20 to 23 years, and their visual acuity ranged from 0.1 to 1.5. The scattering light on fovea was affects by radiance spectral distribution. Even if the colour we recognize was different, when the each colour's the radiance spectral distribution was similar, the significance difference wasn't shown in each colour's scattering light. In the visual environment design, it is important to be considered that spectral distribution of a light source and the spectral reflectance of a material.
