Patent number: 7901074Abstract: In a lens for safety glasses of the present invention, a first lens element which shields a laser beam is laid on a second lens element for antiglare. The first and the second lens element may be affixed together. In the lens for safety glasses, the first lens element includes a substrate which contains an absorbent for selectively absorbing a laser beam having a specific wavelength in an ultraviolet wavelength region, a visible light wavelength region or an infrared wavelength legion and is transparent in the visible light wavelength region. The safety glasses with the lens may provide comfortable fit and a good appearance, causes less misjudgment of colors and prevents loss of correct color sense, and has both a laser-beam shielding function and an antiglare function.Type: GrantFiled: December 27, 2005Date of Patent: March 8, 2011Assignee: Yamamoto Kogaku Co., Ltd.Inventors: Tamenobu Yamamoto, Yoshihisa Ishiba, Koichiro Oka

Patent number: 6810536Abstract: Swimming goggles include goggle frames and associated goggle lenses. Each goggle lens has an outer composing layer and an inner composing layer which is unified with the associated goggle frame. The inner composing layer is welded together to an inside face of the outer composing layer. The goggle frame is welded together to a peripheral side face of the outer composing layer. In this way, the goggle frame and the associated goggle lens are unified together. The swimming goggles are free from water penetration between the goggle frames and the goggle lenses, and allow a high productivity and a low incidence of defected products.Type: GrantFiled: May 29, 2002Date of Patent: November 2, 2004Assignee: Yamamoto Kogaku Co., Ltd.Inventors: Tamenobu Yamamoto, Yoshihisa Ishiba, Kazuko Mabuchi

Patent number: 6611966Abstract: Goggles include an inner lens plate, an intermediate lens plate and an outer lens plate. A space between the inner and intermediate lens plates and a space between the intermediate and outer lens plates form heat-insulating layers. The intermediate lens plate has a through hole and at least one of the inner and outer lens plates has a vent hole. The vent hole is covered with a moisture blocking member which prevents moisture from passing and allows air to pass.Type: GrantFiled: February 21, 2001Date of Patent: September 2, 2003Assignee: Yamamoto Kogaku Co., Ltd.Inventors: Tamenobu Yamamoto, Tomihiro Funamoto, Kimio Matsumoto
