Abstract: In a synthetic resin lens, a thermoplastic resin is caused to contain a blue pigment having the lowest value for light transmittance in 570-610 nm, and a pink pigment that, among blue light of 380-500 nm, has the highest value for light transmittance in 400-440 nm and the lowest value for light transmittance in 480-520 nm, resulting in a transparent achromatic lens having a lowest value for light transmittance in 570-610 nm. As a result, provided is a synthetic resin lens that, when used in sunglasses, corrective glasses, shields, or the like, has favorable contrast (visibility), few marked color changes when installed, and a natural color.

Abstract: A fog-resistant structure and a protective device for eyes is configured such that a transparent conductive film is formed on one surface of a lens or shield, a linear electrode is provided on upper and lower portions of the surface of the lens or shield so that each of a central region and opposite side regions of the lens or shield has substantially equal spacing between the upper and lower linear electrodes. Thus each region of the lens or shield has no difference in temperature without regulating power supplied to the transparent conductive film, thereby eliminating wasted power consumption and allowing even a structure using a battery as the power supply to have much longer available time.

Abstract: A circularly polarizing plate with a thermally adhering function imparted thereto, a circularly polarizing lens which is reinforced with a backup resin, and is distorted with difficulty, and circularly polarizing glasses. Also provided is a clockwise or counterclockwise circularly polarizing plate including a multilayered circularly polarizing plate having at least a phase difference functional part, a linear polarizing functional part, and a thermally adhering functional part which thermally adheres to a backup resin. The phase difference functional part is arranged on one side of the linear polarizing functional part, and the thermally adhering functional part is arranged on another side. Also provided is a clockwise or counterclockwise circularly polarizing lens, which is a bending-processed product of the above circularly polarizing plate.

Abstract: A protective device for eyes, for example, goggles of a shield, includes a double lens member, a frame member and a face fixation member. The double lens member includes a front lens, a back lens and a gasket. The front lens and the back lens are made of polycarbonate resins, polyurethane resins, polyester resins or polyamide resins. The front lens and the back lens are disposed in parallel with the gasket therebetween in order to form a space surrounded with the front lens, the back lens and the gasket. This device is excellent in the antifogging property in the double lens.

Abstract: An optical structure for eye, for example, ski goggles, has an outer lens and an inner lens disposed in parallel. A peripheral sealing is provided between and along the entire circumferential edges and their surroundings between the lenses. Between the lenses is a room defined by the rear face of the outer lens and the front face of the inner lens and an inorganic film is provided on the rear face of the outer lens and/or the front face of the inner lens. The inorganic film is prevented from peeling of due to external factors.

Abstract: The present invention provides an earplug which can reduce resistance force of the water, rain and wind, and a time loss due to the resistance force in sports competing for speed and which is not dropped due to reduction in its holding power and which can reduce vibration sound generated when something touches or hits the earplug, prevent the vibration sound from being transferred to the ear hole of a user and protect a sense of hearing satisfactorily. Furthermore the present invention provides a headgear with the earplug in order to prevent the earplug from being dropped and lost or left behind. The earplug of the present invention is characterized in that the earplug body is connected to an arm 2 at an angle of 90±45°. The arm 2 to which the earplug body 1 is connected at the angle of 90±45° is connected to one end of a cord 3. Arms 2 and 2 to which earplug bodies 1 and 1 are connected at an angle of 90±45° are connected to both ends of cord 3.
