The RUBI glasses developed are specially coated versions that specifically reflect the color spectrum of blood and display it in the color black. Other colors, including other red as well as yellow from warning signs, etc., continue to be displayed and perceived almost originally – for greater safety at the scene!
In principle, nothing changes in the situation of an operation in case of bad accidents, but the disturbing image loses intensity due to the conversion of the red color of the blood into neutral black and gray. This prevents the automatic long-term storage of these images in the brain.
