Patent number: 11768316Abstract: A new ocular contact lens has been designed to increase the amount of light reaching the retina. The contact lens edge is chamfered to redirect and increase the light reaching the retina. A light source encircles and contacts the straight or curved chamfered edge. Additionally, a reflective cylinder and its top wall encircle the lens to block any loss of light. This distal edge of the contact lens may be rounded to increase the angle of retina visible. A new ocular imaging camera has a low-light camera subassembly with server, a photosensor next to low-light camera, a short cylindrical housing, a space between the camera subassembly and the housing, an internal program in server to detect good or poor image quality and an alarm for poor image quality, wherein an operator recaptures the image. A system has a highly efficient method to screen and diagnose a large number of patients using the new ocular contact lens and ocular imaging camera. The system receives and processes the photographs.Type: GrantFiled: October 14, 2019Date of Patent: September 26, 2023Assignee: Preventa Medical CorporationInventors: Ramin Schadlu, Zhijie Chen

Patent number: 10078230Abstract: Eyeglass lenses have at least a portion of their edge shaped to reflect light away from an eye of a wearer, such as the edge being disposed at an acute angle with respect to a principal axis of the lens, toward the back surface of the lens. Alternatively or additionally, the edge may include a plurality of edge surfaces disposed at an acute angle with respect to a principal axis of the eyeglass lens, toward the back surface of the eyeglass lens, or at least one edge surface may be disposed at an acute angle with respect to the front surface of the lens and at least one other edge surface may be disposed at an acute angle with respect to the back surface of the lens. As yet another alternative, the edge may be rounded with progressive angles to have an edge axis directed away from the wearer's eye.Type: GrantFiled: May 20, 2014Date of Patent: September 18, 2018Assignee: Essilor InternationalInventor: Peiqi Jiang

Publication number: 20150109572Abstract: The present invention relates to a beveling wheel and method for forming a beveled lens with the beveling wheel for use with eyeglasses. One embodiment includes a prescription lens for use on an eyeglass frame having a receiving channel. The receiving channel includes a channel bottom and opposed interior wall surfaces having a first angle therebetween. The prescription plastic lens includes a prescription lens body generally defined by a peripheral edge having a bevel extending away from the edge to a vertex. The bevel has a distal portion with a second angle. The bevel is receivable within the receiving channel. At least a portion of the vertex of the bevel has an interference fit with the receiving channel bottom when held within the eyeglass frame. The first angle is greater than the second angle.Type: ApplicationFiled: January 5, 2015Publication date: April 23, 2015Inventor: Ronald C. WIAND
