Practicing fire scenarios in emergency response training is very hard due to various obstacles. An example is when holding a training, real fire will preferably not be used as it can become threatening. Real fire will only be used in a surrounding where safety is ensured, which is probably outdoors. An emergency responder hardly knows that it has entered an area or room with imaginary fire nor does he know the extent of the fire due to the absence of smoke. This makes it exceedingly difficult to make right decisions during the training on the spot and this might lead to failure to help employees or clients to escape the fire area or building. This project focuses on developing glasses that can darken the view of the user, when entering an area with simulated fire and smoke. In order for the emergency responder to be able to practice in the most real possible scenario. The gain of using the glasses, is that it provides a common understanding between the instructor and trainee about the smoke situation in a training exercise. This enhances the quality of training, decreasing the possibility of making an incorrect decision when a real fire breaks out. This is done by constructing a set of darkening glasses that can darken the view, on the command of an infrared beacon that mimic the source of smoke in an area.
