醫生袍顏色的秘密
提到醫生，腦海裡就出現身穿白袍、頸掛聽診器的典型模樣，仔細再想，出入手術室的醫生都穿藍綠色的手術服啊，又是為甚麼呢？是想讓病人眼睛看得舒服一點嗎？當然不是呢！
追溯至19世紀時，當時醫療技術並不完善，醫生質素良莠不齊，一般人對醫生並不信任，醫生多穿著黑色衣服行醫就像神職人員一樣。後來來自英國的醫生Joseph Lister，提倡消毒觀念的重要性，並提出醫生穿著白袍讓髒污一目了然，建立了醫生的專業形象。
至於醫生進手術室都換上藍綠色的手術服，是為了能更精準地進行手術，手術時醫生長時間凝望著血紅色的組織和器官，很容易產生視覺疲勞，分辨紅色細微變化的能力會下降，望望藍綠色可以紓緩一下眼睛的壓力，以及保持對紅色的敏感度；同時藍綠色可以將「視覺暫留」問題減到最低，因為眼睛長時間看一種顏色，轉移視線看別的地方時，眼睛會出現剛才那種顏色的互補色，紅色的互補色就正是藍綠色；最後，藍綠色手術服沾到血液時會呈現成啡色，相比血濺在白色袍上，能減低視覺上的衝擊。
The history of lab coat colors
When it comes to doctors, the first thing that comes to mind is their classic white lab coar and stethoscope around their necks. But if you think carefully, the doctors in operating room actually wear blue-green scrubs. Why is that? Do they want to make patients’ eyes more comfortable? Definitely not!
Back in the 19th century, when medical technology was less developed, the quality of doctors were not high. People did not trust doctors. Doctors dressed in black clothes that looked similar to clergymen. Later, Joseph Lister, a doctor from the United Kingdom, advocated the importance of disinfection, and suggested that doctors wear white lab coats so you can clearly see any dirt. This established the professional image of doctors.
As for the doctors in the operating room, they change to blue-green scrubs in order to do surgery more accurately. During the surgery, the doctors at looking at the blood-red tissues and organs for a long time, and that can lead to visual fatigue. The ability to recognize the subtle changes in red will be affected. Looking at blue-green can ease the pressure on the eyes and keep sensitivity to red. Meanwhile, blue-green can minimise the problem of "persistence of vision", as the eyes look at one color for a long time and then shift to something else, it will appear complementary colors of the color you looked before. The complementary color of the red is blue-green. The blue-green scrubs also appear brown when stained with blood, making it less visually impactful than on white.
