Abstract: An eye protection device in one embodiment composed of a foam rubber-like member having a front portion, first and second side portions, and first and second apertures therein for receipt of the lenses and frame of a pair of eyeglasses with the side earpieces of the pair of eyeglasses being passed through the first and second apertures in the first and second side portions. When worn, the foam rubber-like member is compressed against the wearer's face to create a seal between the device and the user's face.

Abstract: In a method for manufacturing plastic frames for eyeglasses a plastic blank is provided with formed portions in the area where protruding parts of the finished plastic frame are located. Preferably, these formed portions are injection molded onto the plastic blank. By providing these formed portions to the plastic blank, the number of commonly required cutting steps are reduced.

Abstract: An eyeglass frame (10) constructed of a single continuous hollow transparent thermoplastic tube configured to successively define a first temple piece (12), a first lens frame (14), a nose bridge portion (16), a second lens frame (18), and a second temple piece (20). The hollow inner chamber passage of the tube is filled with a colored liquid so as to impart the color of the liquid to the eyeglass frame. The free ends (24, 26) of the temple pieces (12,20) may be provided with removable plugs (28,30) so that the color of the liquid in the passage may be changed, or the free ends of the temple sections may be permanently sealed (12a) to permanently seal the liquid within the hollow passage.

Abstract: The invention provides a spectacle frame having on its inner (rear) face a circumferential channel, and frame-to-face seals carrying a mating ridge on the outer (forward) face of each seal. The spectacle frame is converted to an air-vented safety goggle, to a watertight swimmer's goggle or to an underwater diving mask by mating the appropriate frame-to-face seal with the channel in the frame; the frame can carry plano or prescription ground lenses and may be provided with temples or with an elastic headband.

Abstract: This invention relates to variable focus eyeglasses comprising flexible and rigid optical components. The rigid components act as molds which modify the optical properties of the flexible components when the flexible and rigid components are engaged.At least one of the flexible or rigid components is movable along an anterior-posterior axis, resulting in the distortion and restitution of a flexible component by one or more rigid components thereby altering the optical properties of the system.A spring mechanism located in the nosepiece or bridge portion of the eyeglasses may be used to facilitate the anterior-posterior movement of the movable components.

Abstract: A spectacle structure for wear during active sports where eye protection is desired includes a protective panoramic or wrap-around frame and portions snugly engaging spaced parts of the head to support the frame on the head of a person. Lenses, such as prescription lenses, are fitted into the frame with removable transparent guard lenses thereover and spaces are provided for ventilation of the lenses and the person's eyes to aid in remedying condensation and discomfort.

Abstract: Safety spectacles have an inner frame of hard elastic plastic material extending from one end piece, across the bridge to the other end piece. The base plates for the side piece hinges are embedded in the inner frame. A continuous wire is embedded in the inner frame. The inner frame is completely covered with a soft, elastic, polyurethane foam several millimeters thick which determines the shape of the spectacles.

Abstract: A pair of decorative sunglasses has temples of chain or cord, each sized to extend, when worn, over and behind the ears and down to the ear lobe and to connect to a pendant suspended therefrom. As a modification, the sunglass frames and pendants are formed of transparent material with separable mating halves which snap apart and together to permit changing a decorative sheet which fits between the halves.

Abstract: Warpage-free spectacles comprised of plastic lenses and plastic frames wherein the frames are constructed of materials having the same or lower tensile elastic modulus and/or the same coefficient of thermal expansion as the lens material.

Abstract: A spectacle or eyeglass frame that is especially designed such that when placed down the lenses thereof are protected from coming in contact with the surface thereby avoiding scratching.
