Explanation:
For doctors in the operating room, they often have to concentrate highly on internal organs and blood, and the surgery lasts for many hours. Therefore, to limit the phenomenon of "blue illusion" that occurs, people need to add more blue around the room. Therefore, all the tools and objects in the room from lights, curtains, clothes, even the walls in the operating room are painted light blue to reduce eye strain and help doctors to regulate their eyes better during the surgery.
Another factor explaining why surgeons wear blue is that when you look too long at red or pink internal organs, it will make the brain tired, thereby causing the eyes to be dazzled and not see clearly. At that time, if the above phenomenon occurs, doctors just need to shift their eyes to light blue objects, which will help improve the eyes.
Therefore, the color blue not only helps improve and reduce pressure on the eyes, but it also helps the brain maintain its sensitivity to red, while increasing the accuracy of surgery.
