Eyeglass device, prescription lens, and method of optimizing visual acuity for prescription lens wearers

Abstract

The present invention provides a pair of prescription lenses suitable for use with a near-eye display, the pair of prescription lenses comprising a first lens and a second lens, the first lens comprising a region of first power and the second lens comprising a region of second power, The first focus area is adjusted to a focal length to focus an image displayed by the near-eye display, and the second focus area is adjusted to a focal length that is substantially the same as the focal length of the first focus area The present invention also provides an eyewear device for use with a near-eye display; and a method for optimizing the visual acuity of a wearer of prescription eyeglasses while viewing an image produced by a near-eye display. The present invention enables optimized use of near-eye displays while preventing visual fatigue and other undesirable side effects.

[0002] This application claims priority to the U.S. Provisional Patent Application Serial No. 61 / 922,495 filed on December 31, 2013, and the content of the U.S. Provisional Patent Application is incorporated herein by reference in its entirety. Technical field

[0003] The present invention relates to a pair of prescription eyeglass lenses, and more specifically to a pair of prescription eyeglass lenses optimized for display images used in conjunction with a near-eye display device, eyeglass devices containing such prescription lenses, and to improve Visual acuity method. Background technique

[0004] Current lens designs (regular or digital) are mainly used for distance vision and for near vision in the case of multifocal and progressive lenses. For lenses intended to be used in conjunction with visualization devices that display images (e.g., heads-up displays, retinal projectors, or other near-eye systems), the visualization elements are usually mounted ...
