Methods and apparatus for eye relaxation
First Claim
1. A method of presenting stimuli to a human who has a first eye and a second eye, which method comprises using optical apparatus to display a first set of visual stimuli to the first eye to change accommodation of the first eye, while using the apparatus to display a second set of visual stimuli to the first or second eye to measure refractive aberration of the first or second eye, wherein:
- (a) the second set of visual stimuli (i) includes light that passes through a first region of a mask and (ii) includes light that passes through a second region of the mask, which first and second regions of the mask do not overlap each other; and
(b) the method further comprises using one or more color filters to cause the light that passes through the first region of the mask to be only light of a first set of colors and the light that passes through the second region of the mask to be only light of a second set of colors, wherein the first and second set of colors do not fully overlap.

Abstract
In exemplary implementations of this invention, a bi-ocular apparatus presents visual stimuli to one eye of a human subject in order to relax that eye, while measuring refractive aberration of the subject'"'"'s other eye. Alternately, a monocular device presents stimuli to relax an eye while testing the same eye. The apparatus induces eye relaxation by displaying virtual objects at varying apparent distances from the subject. For example, the apparatus may do so by (i) changing distance between a backlit film and a lens; (ii) using extra lenses; (iii) using an adaptive lens that changes power; (v) selecting distinct positions in a progressive or multi-focal length lens; (vi) selecting distinct optical depths by fiber optical illumination; (vii) displaying a 3D virtual image at any given apparent depth; or (viii) display both a warped version of the real world and a test image at the same time.

11. Apparatus for presenting stimuli to a human who has a first eye and a second eye, the apparatus comprising in combination:
-
(a) a first light source; (b) a second light source; and (c) a plurality of optical elements, including (i) a mask, and (ii) one or more color filters; wherein (i) the plurality of optical elements are configured to modify light from the first light source to display a first set of visual stimuli to the first eye to change accommodation of the first eye, while modifying light from the second light source to display a second set of visual stimuli to the first or second eye to measure refractive aberration of the first or second eye, (ii) the mask is positioned such that the second set of visual stimuli (A) includes light that passes through a first region of the mask and (B) includes light that passes through a second region of the mask, which first and second regions of the mask do not overlap each other, and (iii) the one or more color filters are configured to cause the light that passes through the first region of the mask to be only light of a first set of colors and the light that passes through the second region of the mask to be only light of a second set of colors, wherein the first and second set of colors do not fully overlap. - View Dependent Claims (12, 13, 14, 15)
