Question

why docters are used in green colour dress?

Answer 1

Scrubs used to be white — the colour of cleanliness. Then in the early 20th century, one influential doctor switched to green because he thought it would be easier on a surgeon’s eyes, according to an article in a 1998 issue of Today’s Surgical Nurse. Although it is hard to confirm whether green scrubs became popular for this reason, green may be especially well-suited to help doctors see better in the operating room because it is the opposite of red on the colour wheel.

Green could help physicians see better for two reasons. First, looking at blue or green can refresh a doctor’s vision of red things, including the blood innards of a patient during surgery. The brain interprets colours relative to each other. If a surgeon stares at something that’s red and pink, he becomes desensitised to it. The red signal in the brain actually fades, which could make it harder to see the nuances of the human body. Looking at something green from time to time can keep someone’s eyes more sensitive to variations in red, according to John Werner, a psychologist who studies vision at the University of California, Davis

Answer 2

Second, because the doctors vision continuously focused on the red colored patient's organ, where the red color can cause green colored optical illusion on the white colored surface and certainly can be annoying. This optical illusion appears when doctors shifted their gaze from the red colored body tissue to something white. Green colored optical illusion of the patient's internal organs will appear on the white colored background. This optical illusion occurs because white color has all the spectrum of colors, including green and red color. However, if the doctor saw the green or blue colored clothes and not white, the illusion that interfere would be the right blending with the color of clothes and not be a distraction.
