A temple adjustment mechanism (26) includes a male side member (30) joined to one side of a rim (14), and a female side member (32) relatively movable to and from the male side member. A temple (24) is hingedly connected to the female side member. The male and female side members are relatively movable between a retracted position and an extended position. A spring (50) is connected between the male and female side members to hold the two side members in their retracted position. A linkage (56) extends between the male and female side members and is manually operable to move the two side members to their extended position from their retracted position. When the male and female side members are moved to their extended position, the female side member is longitudinally spaced from the male side member so that the overall length of the temple is increased.
