Why are surgical gowns green or blue?
Doctors who relieve patients have always been known as "angels in white", and they are synonymous with medical workers. However, I don't know if you have noticed that doctors put on green surgical gowns when they perform operations, so why is it not white?

It is not difficult to imagine that doctors spend most of the operation time focusing on blood-red tissue or organ work. In this case, the doctor's brain is prone to "oversaturation". That is to say after the brain is continuously exposed to the same kind of things or the same stimulation, it will produce neural fatigue. With the advancement of the operation time, the doctor's eye's ability to distinguish red will gradually decline, and then the subtle difference between red in various parts will be unable to distinguish, so at this time, it is necessary to shift the eyes to green from time to time to keep the brain's awareness of red sensitivity.
