Why do pilots wear red goggles at night?
By using red lights or wearing red goggles, the cones can receive enough light to provide photopic vision (namely the high-acuity vision required for reading). … Similarly, airplane cockpits use red lights so pilots can read their instruments and maps while maintaining night vision to see outside the aircraft.
