Abstract :
Two types of new effective instruments for recovering the visual strain of the VDT operator caused by continuous VDT operations are described. Both the instrument for measuring the achromatic color using the complementary color and the instrument for measuring the recovery of the visual accommodation function using the picture of virtual far point, are developed. These two kinds of instruments are useful for the recovery of visual strain
