Problems solved by technology

Standard prescription lenses are not designed to optimize visual acuity to the displayed image in those very near gaze directions, which results in blurring of the image display and vision as the eye tries to compensate for movement to the unclear viewing area fatigue

Embodiment Construction

[0023] The present invention relates to an inventive method and device, which relates to prescription eyeglass lenses optimized for display images used in conjunction with near-eye displays; eyeglasses containing such prescription lenses optimized for display images; and to improve vision when using such displays Sensitivity method. As used herein, near-eye display means a display, device, or system that is usually worn on the head of a user to generate images near the eyes, such as a retinal projector, virtual retinal display, visualization element, head-mounted display, head-up Display, or other near-eye system. The display device is usually installed adjacent to the edge of the wearer's eyes and therefore located close to the wearer's pupils. Therefore, the position of the display forces the wearer to stare in one direction to observe the image produced by the display. Since it is usually located close to the user's eyes, the display is aligned with the user's field of vie...

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.

Description

[0001] cross reference [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 ...
