Patent number: 8795838Abstract: A composite material for optical use as well as the method for obtaining it. This material includes a substrate made from a thermoplastic copolyester, a layer of polyurethane bonding primer, and a silicone anti-scratch varnish; advantageously, this varnish has hydroxyl groups, aliphatic CH groups, ester groups, and siloxane groups without methyl groups. This material makes it possible to produce optical pieces, in particular sunglasses, particularly solar glasses, as well as eyeshades for helmets or masks.Type: GrantFiled: March 4, 2011Date of Patent: August 5, 2014Assignee: Christian Dalloz SunopticsInventor: Franck Montalbano

Patent number: 8449109Abstract: A new type of lens for eyeglasses and a method for obtaining the same. The lens is composed of a transparent substrate; a composite layer disposed between the substrate and a layer of precious metal, such as gold, the composite layer is composed of at least two layers. A combination for the composite layer is an anti-reflective layer applied directly to the substrate and made of a metal such as chromium; the anti-reflective layer is advantageously made of silicon oxide.Type: GrantFiled: April 29, 2009Date of Patent: May 28, 2013Assignee: Christian Dalloz SunopticsInventors: Laurent Maisonhaute, Nathalie Boyer

Publication number: 20090130428Abstract: A substrate made of a transparent inorganic or organic material, with transparent elements distributed through its volume, even in the visual field of a wearer of said substrate, and incident light is partly reflected and partly transmitted. The elements may undergo surface treatment to render them even more light-reflecting. A method of producing the above substrate and an application of the above substrate as optical elements.Type: ApplicationFiled: October 28, 2008Publication date: May 21, 2009Applicant: CHRISTIAN DALLOZ SUNOPTICSInventors: Herve Meillat, Nathalie Boyer, Nicolas Parent

Patent number: 6554421Abstract: A nonconnecting lens blank and method provide an integrated optical function insert and allow for ease in trimming by the ability to visually orient the geometric alignment of the optical function insert. The nonconnecting lens blank has an inner concave face (2c) and an outer convex face (2b) delimited by a peripheral border (2a). A matrix (4) of transparent material transmits light from the outer face towards the inner face. An insert (6) integrating the optical function is placed in one of the faces of the matrix. The matrix may include a housing (5) in which the insert (6) is fitted. The insert (6) preferably has two truncated concentric circular edges (5a1, 5a2) separated by two straight parallel edges (5a3, 5a4). The optical function may be polarization with the plane of polarization aligned relative to the straight edges.Type: GrantFiled: May 29, 2001Date of Patent: April 29, 2003Assignee: Christian Dalloz SunopticsInventors: Etienne Billard, Alain Ravier

Patent number: 6540352Abstract: This lens is mounted in a frame having two earpieces and composed of two spherical surfaces (6, 8) and an optical center. In the standard wearing position in which a horizontal line connects the center of the pupil of the eye to an area of the ear on which an earpiece of the frame rests, the optical axis defined by the line passing through the two centers of the spherical surfaces makes an angle of at least 10° with a horizontal axis.Type: GrantFiled: February 22, 2001Date of Patent: April 1, 2003Assignee: Christian Dalloz SunopticsInventors: Etienne Billard, Alain Ravier

Patent number: 6138286Abstract: A goggle has a replaceable plastic lens mounted in a flexible frame containing several air vents for passing external air through the goggle interior. The lens is formed of thermoplastic materials to provide spherical and cylindrical versions of the lens. The thermoplastic resins incorporate dyes which tint the lens to create transmission curves having peaks and valleys which approximate or enhance certain response characteristics of the retina of the human eye. Inlet air vents are covered by porous foam located in an upper air channel to disperse downwardly the external air into the interior space behind the lens. Outlet vents located in the bottom of the frame are covered with a porous foam to exit air from the interior space.Type: GrantFiled: April 14, 1999Date of Patent: October 31, 2000Assignees: Scott USA, Inc., Christian Dalloz SunopticsInventors: David T.
