Foggles manufactures glasses that are used as a tool during the pilot training process. The glasses are designed to limit the pilot's field of vision. This assists the learning process by encouraging the pilot to fly with only the help of the flight instruments. In instances when flying at night or in inclement weather, the pilot needs to be able to land with no visual aids external to the craft. Foggles produces pilot training glasses that meet all Instrument Flight Rule (IFR) certification requirements.
