In fact, the medical staff in the operating room also wore white uniforms until a doctor discovered the drawbacks of the white uniforms. When the doctor turned his gaze from the red blood to the white uniform, his eyes suddenly became invisible. Just as when you go out in winter, you may be dizzy suddenly when you see the sunlight reflected from the snow. Under such visual interference, doctors are likely to make mistakes.
To put it simply: if you look at a color for a long time, when you look at other places, you will see a color that is complementary to the previous color. Psychologically, this is called the visual afterimage. The role of green and blue is to help doctors refresh the impression of red in vision, so that the brain is not desensitized to red. In fact, it is very simple to do this, as long as you look at something green from time to time during the operation. It is obviously more convenient to put the “green” on each other than to find some green things to put them somewhere in the operating room.
Therefore, using green and blue as uniforms can improve the visual acuity of doctors and also allow them to see different shades of red. This can help doctors focus on distinguishing the various nuances of the human body during the operation and reduce the possibility of making mistakes during the operation.
Coupled with the operation, it is easy to get red blood stains. If you wear a “white coat”, blood stains on the uniform will cause a bloody visual impact.
Wearing green and blue uniforms will turn into black or brown even if blood stains on the uniform, thus playing a role in visual adjustment.
