Ever wonder why they wear green or blue scrubs in the operating room?

 It may seem trivial, but this experience can determine the success of the surgery. Surgeons did not always wear scrubs in the operating room. It wasn't until the 1918 flu pandemic and disinfection theories that led to the use of surgical masks, rubber gloves, antiseptic curtains, gowns, and hats. operating room. Soon, surgeons began to wear white during surgery to associate it with the color of innocence. The assistant prepares the doctor for the operation
Around this time, at the beginning of the 20th century, surgeons began to realize the problem of seemingly harmless white surgery. The problem is that the pure white color can make a surgeon wonder for a moment when he sees the dark color of blood on a colleague's operating table. When you go out in winter for the first time, the same effect is achieved when the sunlight reflects off the snow.

During the operation, the doctors looked too long at their colleague's white operation and had headaches. According to a 1998 article in Surgical Nurse Today, in 1914 an influential doctor switched to green surgery because he thought it would be better for the eyes during surgery.

Eventually, surgeons around the world began replacing white operations with blue or green ones. It also made it easier for hospital staff who had to perform the very difficult task of removing bloodstains from doctors' clothes.

However, it is still not explained why the surgeons chose green and blue instead of purple or yellow for the operation. Because green and blue are opposites of red in the visible spectrum, surgeons almost always focus on red during surgery. Green is the exact opposite of red on the color wheel, making it ideal for doctors to see better in the operating room. In this sense, green and blue colors not only help surgeons improve their vision, but also make them more sensitive to different shades of red. This allows you to pay more attention to the nuances of human anatomy, which greatly reduces the chance of errors during surgery. 

Another reason has to do with the surgeon's deep focus on red during surgery. 

Red can create an unsettling green illusion on a white surface. So if the surgeon moves his gaze from the bloody organ to the white lab coat, a green ghost of the patient's red abdomen may appear against a white background. The image in question resembles a surgeon floating wherever he looks for a camera flash. This happens because white light contains all the colors of the rainbow (red and green). However, the red pathway is still tiring, so the brain's red and green pathways provide 'green' signals. According to Paola Bressan, who studies optical illusions at the University of Padua in Italy, when a doctor sees a green or blue pattern instead of white, this disturbing image is immediately resolved and becomes a problem.
