We all know that doctors wear disposable surgical gowns during surgery, and the most common ones are green or blue. So why are the surgical gowns in the operating room all green or blue? There are four main reasons:
1. Avoid the interference of complementary color afterimages and ease the visual pressure. People stare at one color for a long time, and then look at other places. In order to get their own balance, the eyes produce a complementary color as an adjustment. During the operation, the doctor holding the knife for a long time focuses on the scarlet blood and suddenly changes his sight. The afterimage of the complementary color produces the feeling of seeing green. At this time, if the surgical gowns are white, they will be affected by the green produced by the afterimage of the complementary color, which will lead to the inability to concentrate; however, if the doctor wears green or blue surgical gowns, It can avoid the visual pressure caused by complementary color afterimages.
