There is provided a system and method for following and conducting laboratory procedures for preventing errors and fatigue of the user. The system involves input means, such as a microscope, and a camera connected to the input means, while the camera creates images of the input means. A computer is connected to the camera, and it processes the images so that augmented reality glasses which are also connected to the computer, are capable of having those images projected thereon. The computer also has laboratory protocol files installed thereon, and it projects images of the protocols onto the glasses. The projected images do not interfere with a user's natural vision.
