• The age-related vision change affects elderly safety and quality of life. Cataract is one of the common causes that alter color perception of elderly. The serious problem of the cataract eye is scattering of environment light into the eye. These researches aim to study color vision of elderly relating to the size of the color patches, degree of fogginess and environment light. The simulating technique using goggles with various degree of hazes were employed. The experiment conducted with the 47 elderly was also included. Results of the experiment show that the scattering light causes desaturation of the color appearance to the elderly. The higher the degree of haze the more desaturation occurs. The size limits of the color patch depend on the colors. And to perceived object color mode correctly is 6 degrees of visual angle. The red and yellow are the colors which the elderly can perceive correctly than the other colors, in all experiment sizes. The experiment results from both techniques agree with each other.
