Abstract
An eyecup (24) for interfacing a night vision goggle (10) with the eyes of the user (12). A flexible curved eyepiece (28) including a wing (38) provides a tight seal of the periphery of the eyepiece (28) to the occular eye area of the user (12). The seal prevents light (22) emitted from the goggle (10) from escaping out of the confines of the eyecup (24). A fastening sleeve (26) is provided to secure the eyecup (24) about a flange on the goggle (10). An intermediate accordion section (40) allows compression and expansion and maintains the seal between the eyepiece (28) and the ocular eye area. An air vent hole (52) is formed in the accordion section (40) to prevent suction from occurring within the eyecup (24).
