A vapor-permeable, vented eyecup for night vision goggles and other optical devices having an eyepiece. An eyecup is used to create a light tight seal between the eyepiece and the operator's face. In addition to containing the light from the optical device, the eyecup blocks out external light. When viewing through an optical device using a non-vented eyecup, moisture becomes trapped in the eyecup volume bounded by the operator's eye socket, eyecup, and eyepiece. Fog forms on the eyepiece as a result. This invention reduces the occurrence of fogging by allowing moisture to vent out of the volume through a vapor permeable material. This material allows vapor to pass but blocks larger water droplets, dust, dirt, and light.
