Contact lens device for displaying augmented or virtual reality

Abstract

Configurations are disclosed for presenting virtual reality and augmented reality experiences to users. The system may comprise an image-generating source to provide one or more frames of image data in a time-sequential manner, a light modulator configured to transmit light associated with the one or more frames of image data, a substrate to direct image information to a user's eye, wherein the substrate houses a plurality of reflectors, a first reflector of the plurality of reflectors to reflect transmitted light associated with a first frame of image data at a first angle to the user's eye, and a second reflector to reflect transmitted light associated with a second frame of the image data at a second angle to the user's eye.

What is claimed is: 
     
         1 . A contact lens to interface with a cornea of an eye of a user of a virtual or augmented reality display, the contact lens comprising:
 a partially hemispherical substrate and a selective filter, wherein the selective filter is configured to selectively pass light beams to a user's eye.   
     
     
         2 . The contact lens of  claim 1  wherein the selective filter is a notch filter. 
     
     
         3 . The contact lens of  claim 1  wherein the notch filter substantially blocks wavelengths at approximately 450 nm (peak blue) and substantially passes other wavelengths in a visible portion of the electromagnetic spectrum. 
     
     
         4 . The contact lens of  claim 1  wherein the notch filter substantially blocks wavelengths at approximately 530 nm (green) and substantially passes other wavelengths in a visible portion of the electromagnetic spectrum. 
     
     
         5 . The contact lens of  claim 1  wherein the notch filter substantially blocks wavelengths at approximately 650 nm and substantially passes other wavelengths in a visible portion of the electromagnetic spectrum. 
     
     
         6 . The contact lens of  claim 5  wherein the notch filter comprises a plurality of layers of dielectric materials carried by the substrate. 
     
     
         7 . The contact lens of  claim 5  wherein the filter has a pinhole opening of less than 1.5 mm diameter. 
     
     
         8 . The contact lens of  claim 7 , wherein the pinhole opening allows light beams of a plurality of wavelengths to pass through. 
     
     
         9 . The contact lens of  claim 5 , wherein a size of the pinhole is varied based at least in part on a desired depth of focus of the display. 
     
     
         10 . The contact lens of  claim 5 , further comprising a plurality of modes of operation. 
     
     
         11 . The contact lens of  claim 5 , further comprising a multi-depth of focus display configuration of the virtual content. 
     
     
         12 . The contact lens of  claim 5 , further comprising an accommodation tracking module to determine an accommodation of the user's eye. 
     
     
         13 . The contact lens of  claim 5  wherein a depth of focus of a particular display object is varied based at least in part on the determined accommodation. 
     
     
         14 . The contact lens of  claim 5 , wherein an image is relayed through a waveguide, the relayed image associated with a particular depth of focus.
