Abstract: An apparatus configured to fog test eyewear includes an environmentally controlled chamber, a head form disposed within the chamber, a radiator disposed within the chamber, the radiator connected to a liquid cooling system, and a humidifier device configured to deliver a flow of warm moist air towards the frontal portion of the head form and a surface of the eyewear. A camera is disposed within the head form, the camera aligned with a first opening in a frontal portion of the head form and configured to detect a target image within the chamber while the flow of warm moist air is delivered. A processor is configured to calculate a contrast difference between a background of the target image detected by the camera and resolution bars of the target image detected by the camera, plot a contrast ratio from the calculated contrast difference against a known calibration standard and calculate a performance measure of an anti-fog device of the eyewear.
