| Abstract: |
A spectacle structure having a plurality of flexible portions formed in head engaging components thereof is disclosed wherein the flexible portions permit unidirectional bending of the head engaging components of the spectacle structure to thereby conform to and exert inwardly directed pressures on the head of the person to support the spectacle structure thereon, said spectacle structure engaging the head portions for support with an absence of support by the nose or ears. The spectacle structure includes lens means depending from a front frame member and a pair of elongated temple members hingedly connected to respective opposite end portions of the front frame member. The head engaging components of the spectacle structure are of a combined length such that one of the temple members is in crossing and overlying relation with the other of the temple members when in an open and relaxed position.

What I claim and desire to secure by Letters Patent is:
1. A spectacle structure comprising:
- a. a front frame member having portions engaging a forehead of a person wearing the spectacle structure at a level adjacent to the eyebrows, said front frame member having opposite end portions and a length positioning same at respective sides of a person's forehead, said front frame member having a center portion and portions of reduced thickness adjacent each of said end portions thereof to define respective flexible portions to permit unidirectional bending toward and away from the person's head;
- b. lens means connected to and supported by said front frame member; and
- c. a pair of elongated temple members each having one end portion thereof connected to a respective one of the opposite end portions of said front frame member, said temple members being adapted to extend rearwardly from said front frame member and terminate in rear free end portions, said temple members each having a center portion and first and second portions of reduced thickness adjacent the center portion thereof to define respective flexible portions to permit unidirectional bending toward and away from the person's head, whereby said front frame member and said temple members conform to and exert inwardly directed pressure on a person's head to support the spectacle structure thereon.
