As soon as you step into the operation theatre, the first thing that strikes your eyes is the green and blue colors all around. Why do doctors, nurses, curtains, bedsheets all appear to be in the same color family? Is this just tradition or is there some deep scientific mystery hidden behind it? If surgery involves saving lives, then what is the role of colours? The answer to this question lies in the amazing coordination of medical science and human eyes. Let us know.
Rules related to patient safety
In almost every hospital in the world, doctors wear green or blue scrubs during surgery. This scene has become so common that people consider it a tradition, but in reality there are solid scientific, psychological and practical reasons behind it. The selection of colors in operation theater is not just for beauty but is directly related to the safety of the doctors’ eyes, mind and the patient.
Journey from white to green-blue
In the initial period, doctors used to wear white coats and white clothes during surgery. Till the beginning of the twentieth century, white color was considered a symbol of cleanliness and purity. But around 1914, some surgeons realized that the constant sight of blood caused strain on the eyes and that the red color on a white background became more stinging. After this, gradually green color started being used instead of white, which later spread to blue.
science of eyes and brain
When human eyes look at a bright color, especially red color, for a long time, they start getting color fatigue. During surgery, doctors have to constantly focus on blood and red tissues. If the surrounding environment is also red or yellow in color, then the eyes have difficulty in seeing things clearly. Green and blue colors are the exact opposite of red, which provides balance to the eyes and maintains visual clarity.
Why not red or yellow color?
Red color is considered most inappropriate during surgery, as it makes it difficult to differentiate between blood and body tissues. At the same time, yellow color can dazzle the eyes in bright light and distracts attention. In an operation theater where every second and every millimeter is important, even this small mistake in colors can become a big danger.
Effect of mental peace and focus
Green and blue colors not only give relief to the eyes but also to the mind. According to psychology, these colors reduce stress and increase concentration. There is immense mental pressure on doctors and medical staff during surgery. In such a situation, an environment of calm colors improves their decision making ability and reduces the possibility of mistakes.
Role of light and reflection
Bright artificial lights are used in the operation theatre. White or bright colors reflect more of these lights, causing additional strain on the eyes. In contrast, green and blue colors produce less reflection and help doctors work for long hours without fatigue.
