Doctors in the operating room frequently have to focus heavily on internal organs and blood, and the procedure can take for several hours. As a result, in order to decrease the “blue illusion” phenomena, people should add more blue to the room. As a result, all of the tools and objects in the room, including lighting, curtains, clothing, and even the operating room walls, are painted light blue to lessen eye strain and assist surgeons in better regulating their eyes during surgery.

Another reason why surgeons wear blue is that looking at red or pink internal organs for too long causes the brain to weary, leading the eyes to become dazzled and unable to see well. If the above situation occurs, doctors only need to shift their gaze to light blue things, which will help improve their eyesight.

As a result, the hue blue not only improves and reduces eye pressure, but it also aids the brain’s sensitivity to red, enhancing surgical accuracy.
