A binocular includes a hood, an eyepiece lens panel, and an objective lens panel. The hood has top, left side, and right side portions that are integrally formed. The left and right side portions have free edges that extend downwardly from the top to form an open bottom. The open bottom of the hood allows the hood to flex when an outwardly directed force is applied so that the left and right sides can be further separated from one another. This separation allows the eyepiece lens panel and the objective lens panel to be inserted within the hood during assembly of the binoculars to be held by the hood. The eyepiece lens panel has a flat plate frame and two lenses that are integrally formed as a one piece construction. The objective lens panel also has a flat plate frame and two lenses that are also integrally formed as one piece. The hood may further include alignment members to secure and align the eyepiece lens panel. The objective lens panel may further include guides to moveably attach the objective lens panel to the free edges of the hood. The objective lens panel can then be slid along directions of the free edges for focusing purposes. In some embodiments, both the eyepiece and the objective lens panel flat plate frames are transparent to further enhance the utility of the binoculars. The lenses may have large diameters to increase field of view of the binoculars and to allow interpupilary distance between the eyepiece lens panel lenses to be fixed.
