The spectacle device further includes a telescopic lens assembly pivotally attached to the spectacle frame which is pivotable between an operative position and a non-operative position. The spectacle device also includes an indexing mechanism for repeatedly orienting the telescopic lens assembly into the operative position from the non-operative position. A support frame for holding the telescopes of the telescopic lens assembly is adapted to be substantially out of a user's forward line of sight when the telescopic lens assembly is in the operative position.
