ABSTRACT:
In a head mounted display (1) an annular body (2) worn generally horizontally about the head of wearer supports a forwardly disposed optical display device (3) adapted to seat on the bridge of the nose of a user. At either side of the body (2) projections (10,11) extend toward respective ear positions. At the free end of the projection (10) earphone means (14) are provided to rotate eccentrically about a thumbscrew 20 at least between a plurality of angular positions. Thus, an ear-pad (15) can move between the position illustrated and positions such as C, D and E shown by chain dotted lines, thereby permitting the position of the earphone means 14 to be altered to accomodate different ear positions of the user.
