I rely
mainly on visual contrast sensitivity of the light and shade, but this
increase in contrast sensitivity with age to reduce the other, such as
visual acuity, peripheral vision, depth perception and vision of the
size is subject to their age. The study found 16 to 30-year-old visual
performance does not differ greatly, and more than 40 years of age is
relatively diminished vision, glare sensitivity with the right lighting
demand is rising, especially in the most significant 46 to 60 years
old. Usually over the age of 50 need more than the 20-year-olds for at
least 2 times the amount of light in order to achieve the same work
with speed and accuracy (Table 3-4). Therefore, lighting design, older
users should make special considerations, such as avoiding the adjacent
space, illumination difference is too large, and to improve face
illumination, and multi-environment combined with indirect soft
lighting. Moreover, given the aging of the eye Color vision, the use of
color in the room, the should make more use of high-chroma colors and
high contrast color, and avoid the use of the blue |
