Patent number: 11833785Abstract: An optical web comprising includes a substrate with an anterior coating applied to the anterior side of the substrate and a posterior coating applied to the posterior side of the substrate. The refractive index of the anterior coating and the posterior coating is less than that of the substrate. A second coating layer may be applied to the anterior coating layer and/or the posterior coating layer, where the second coating layer has a refractive index less than that of the coating layer it is applied to. Additional coating layers may be applied to produce a stack of layers that decrease monotonically in refractive indexes moving outward from the substrate.

Patent number: 11759362Abstract: A tear-off capture system includes an eye protector with a base lens. The eye protector has a retention mechanism mounted on one side, and a support mechanism that supports the eye protector on the head of a wearer. A two-tabbed stack of laminated tear-off lenses mounts to the eye protector via an adhesive. The stack mounts so that the first tab of the stack aligns with the first side of the eye protector and the second tab engages with the retention mechanism. Via the second tab and the retention mechanism, released tear-off layers are directed toward the second side of the eye protector away from the base lens. A capturer helps hold the initially released tear-off layer to the eye protector. An exposed tacky surface on each released tear-off helps hold the subsequently removed tear-off layers.Type: GrantFiled: October 25, 2021Date of Patent: September 19, 2023Assignee: Racing Optics, Inc.Inventors: Bart E. Wilson, Stephen S. Wilson, Maxwell C. Klein

Patent number: 11625072Abstract: A shield that is attachable to a touch sensitive screen is disclosed. The shield may be attached to the touch sensitive screen only at its outer peripheral portion. An air gap is enclosed between the shield and the touch sensitive screen to form a planar air bearing. The shield preferably does not touch the active area of the touch sensitive screen when the user is not touching the shield but only viewing the touch sensitive screen through the shield. This mitigates unwanted optical artifacts such as trapped air bubbles, Newton rings and chromatic interference while maintaining the sensitivity of the touch sensitive screen.Type: GrantFiled: November 18, 2021Date of Patent: April 11, 2023Assignee: Racing Optics, Inc.Inventors: Stephen S.
