Abstract
A vision correction device may include a sheet of transparent material including a converging lens. The converging lens may be configured such that, when the sheet of transparent material is disposed adjacent to a surface, the converging lens refracts light from an image on the surface with an optical power that shortens a viewer's nearpoint distance by an amount that is the same or greater than the reduction in nearpoint distance provided by a 1.0 diopter corrective eyeglasses lens when worn by the viewer.
Claims20
A vision correction device, comprising:
- a sheet of transparent material including a converging lens;
- wherein the converging lens is configured such that, when the sheet of transparent material is disposed adjacent to a surface, the converging lens refracts light from an image on the surface with an optical power that shortens a viewer's nearpoint distance by an amount that is the same or greater than the reduction in nearpoint distance provided by a 1.0 diopter corrective eyeglasses lens when worn by the viewer.
A vision correction system, comprising:
- a sheet of transparent material including a converging lens;
- wherein the converging lens is configured such that, when the sheet of transparent material is disposed adjacent to a surface, the converging lens refracts light from an image on the surface with an optical power that shortens a viewer's nearpoint distance by an amount that is the same or greater than the reduction in nearpoint distance provided by a 1.0 diopter corrective eyeglasses lens when worn by the viewer;
- wherein the vision correction device is configured to be affixed in proximity to a surface of a display of an electronic device;
- and
- a computer-readable medium including instructions for performing one or more functions that facilitate vision correction in conjunction with use of the vision correction device.
