Abstract: A case for retaining eyeglasses of the locking hinge type, has a front side and a rear side joined to form a closed bottom of the case. The top portions of each side are separate from each other, and rest against each other when the case is in a resting, closed position. At least one of the sides has a generally convex outer surface and a corresponding concave inner surface to form a hollow portion within the case. The top perimeters and the bottom perimeters meet to form two junctions at opposite side edges of the case, such that when inward pressure is applied at each junction, the top perimeters move away from each other to open the case, and upon release of said pressure, the top perimeters return to the closed position.
