Definitions

  • Human eyesight sometimes requires correction, and sometimes involves different amounts or types of correction, depending on a selected object being viewed. For example, when the object is at relatively close-range, an amount of refraction to be preferred might differ substantially from when the object is at relatively distant range. For another example, when the object is disposed in a frontal region of a field of view, a user’s eyesight might differ substantially from when the object is disposed in a peripheral region of a field of view. [10]
  • One issue that can arise with respect to eyesight is that a user might spend excessive time viewing close-range objects, such as a computing display or a mobile device (such as a smartphone). Long-term excessive viewing of close-range objects can lead to dry eye effects and/or myopia.
  • Medical personnel sometimes recommend that the user follow a “20-20-20” plan, that is, each 20 minutes looking away for 20 seconds at an object at least 20 feet away. While this can reduce the likelihood of the user developing a dry eye effect or myopia, users can easily forget to practice this procedure.
  • One technique for delaying the onset of myopia is for the user to wear hard contact lenses, such as “K-Ortho” lenses, a relatively large contact lens that covers the sclera and forces the user’s eye into a different shape. These lenses can be worn at night when the user’s eye is not otherwise busy focusing. This can have the effect of squeezing the user’s eyeball into a shape better suited for non-myopic vision. While this technique can be effective at delaying onset of myopia, they can be less effective when the user restarts their day with the same process of staring at close-range objects such as close computing displays or small screens on mobile devices.
  • Another technique for delaying the onset of myopia is to dilate the user’s eyes, such as with atropine.
  • This can have the advantage of providing more information to the retina, as having a larger pupil size allows more light, and thus more information, to enter the user’s eye. This can avoid any need for the user to squint at a small screen, such as on a mobile device.
  • this technique can be effective at slowing progression of, thus delaying onset of, myopia, it has the drawback that it can induce the user to have photophobia in response to having their eyes frequently dilated. This can be particularly painful when the user has their irises eyes dilated, such as during an optometry exam. With some users, the effect can be sufficient strong that they need tinted glasses even when their eyes are no longer dilated.
  • corrective eyewear can include multiple lens regions, such as an upper clear region having little or no refractive effect and suitable for distance viewing, and a lower “reader” region having a refractive effect suitable for close-range viewing (such as when reading a book or viewing a mobile device display). In such cases, it can be desirable to encourage a viewer to direct their vision through a region best suited for viewing those objects selected by to be viewed.
  • lens regions Other types of vision correction might be applied by distinct lens regions and might be appropriate to objects selected for viewing.
  • distinct polarization might be preferred with respect to objects subject to glare, mobile device displays, or laptop/ desktop displays.
  • eyewear can include multiple lens regions, such as a first region having a first polarization effect and a second region having a second polarization effect.
  • it can be desirable to encourage a viewer to direct their vision through a region best suited for viewing those objects selected by to be viewed.
  • Eyewear can be disposed to apply still other types of vision correction, whether dynamically in selected regions (or for regions defined by dynamically selected sets of pixels) or statically in known regions. Similarly, in such cases, it can be desirable to encourage a viewer to direct their vision through a region best suited for viewing those objects selected by to be viewed. Eyewear disposed to apply one or more amounts or types of vision correction can be made usable in one or more selected circumstances, such as reading, operating a vehicle, performing a selected activity for which particular vision correction is optimized, or otherwise as described herein.
  • each of these issues might cause difficulty in aspects of vision correction and in encouraging a user to select a defined portion of a lens in eyewear through which to view a particular object.
  • each of these issues, as well as other possible considerations might cause difficulty in aspects of eyewear for the user might wish to have more than one function or a different function applied at each of more than one portion of the user’s field of view.
  • devices and methods for use, using them are capable of optimizing sensory inputs using lenses divided into distinct portions.

  • This Application describes devices, and methods for using them, capable of optimizing sensory inputs in bright ambient light, such as when using eyewear 110 having multiple viewing regions. For some examples:
  • the eyewear 110 can have multiple regions having distinct refractive properties; this can have the effect that the eyewear 110 can be suitable for either nearer or farther viewing, or for either viewing in a frontal region or a peripheral region.
  • the eyewear 110 can have multiple regions having distinct shading/inverse-shading properties; this can have the effect that the eyewear 110 can be suitable for viewing objects with different shading/inverse-shading or with no shading/inverse-shading.
  • the eyewear 110 can have multiple regions having distinct polarization properties; this can have the effect that the eyewear 110 can be suitable for viewing objects with different polarization or with no polarization.
  • the eyewear 110 can have multiple regions having distinct dynamic visual optimization; this can have the effect that the eyewear 110 can be suitable for viewing objects with different flickering/periodic display properties, or no flickering/periodic display properties.
  • the eyewear 110 can have multiple regions having distinct color balance; this can have the effect that the eyewear 110 can be suitable for viewing objects with different color frequencies or mixtures thereof. Adjusting for light level
  • the eyewear 110 can include a lamp 114 disposed proximally toward the user’s eye with respect to the lenses 111 (such as disposed inside the eyewear), so as to provide illumination viewable by the user without alteration by the lenses.
  • the lamp 114 can thus adjust a coloring or color balance, or a luminance perceived by the user’s eye. This can have the effect that the user’s eye receives a sufficient amount of luminance so that the user’s visual perception is urged from a scotopic (responsive to a low-level amount of luminance) to mesopic (responsive to a mid-level amount of luminance).
  • the user’s visual perception is mesopic, the user can more easily distinguish colors in the user’s field of view, so as to allow the user to perform activities for which color perception is valuable. Examples of such activities can include one or more of:
  • the lamp 114 can be disposed to present an increase in ambient luminance when the lenses 111 are being adjusted to shade/inverse-shade infalling light to reduce glare or other bright light with possible adverse effects on a user’s medical condition, such as migraine or photophobia.
  • the lamps 111 when the lenses 111 are being adjusted to provide color- ing/tinting to increase an amount of green light, such as to treat or ameliorate migraine or photophobia, the lamp 114 can be disposed to present an increase in luminance perceived by the user’s eye; this can allow the user to interpret their field of view using color vision, even when infalling light is heavily skewed toward green light.
  • the lamp 114 can be disposed to provide a relatively small amount of luminance in a broad spectrum of visible light, such as not to degrade the user’s night vision.
  • the lamp 114 can be disposed to provide a greater amount of luminance in a narrow spectrum of visible light, sufficient to urge the user’s eye toward mesopic operation (but not sufficient to either degrade the user’s night vision or to provide enough blue/ultraviolet to increase the likelihood or severity of migraine or photophobia).
  • the lamp 114 can be disposed to provide luminance in a relatively narrow spectrum of visible light, such as light suitable to reduce the likelihood or severity of, or to treat or ameliorate, migraine or photophobia.
  • the lamp 114 can be disposed to provide light in a frequency range of approximately 5OO-56onm (green), which is believed to be helpful with respect to migraine or photophobia.
  • the eyewear 110 can be disposed to be responsive to a user input indicating a likelihood or severity of migraine or photophobia, such as a measure of pain being experienced by the user.
  • the eyewear 110 can also be disposed to record the user input and to associate that input with a set of related parameters, such as ambient environment (including luminance, color balance, allergens, pollution, air pressure and/ or other weather parameters), time of day, season, and/ or other factors known to be associated with migraine or photophobia.
  • the eyewear 110 can be disposed to adjust an amount of luminance from the lamp 114 (down to zero such luminance) so as to urge the user’s eyes to operate in a scotopic mode (as noted, responsive to a low-level amount of luminance). This can have the effect of allowing the user to train their eyesight so as to recognize object color from texture in a black/ white environment, in response to information from the user’s rods, which provide an essentially monochromatic view.
  • the eyewear 110 can be disposed to adjust coloring/tinting, or otherwise adjust color balance, so as to show primarily green light. Showing green light is believed to provide the user with a reduced likelihood or severity of migraine or photophobia; however, showing only green light can have the effect of degrading the user’s ability to see objects or signals which are red. Accordingly, showing primarily green light can be performed once the user’s eyesight is trained to recognize red objects or signals.
  • the lamp 114 can be disposed to illuminate a portion of the user’s field of view as directed by the user’s gaze direction and/or focal length.
  • the eyewear 110 can determine a location at which the user is looking.

  • the eyewear 110 can be disposed to continuously adjust illumination and/or shading/inverse-shading in response thereto.
  • the eyewear 110 can be disposed, in response to a user input, to adjust refraction of the lenses 111 in response to a distance to the location where the user is looking (such as to “zoom in” on that location), adjust shading/inverse-shading to encourage the user to focus on that location, and/or adjust coloring/tinting to ease the user’s view of that location.
  • the lamp 114 can be disposed to be adjusted in brightness or focus to maintain a relatively fixed measure of total brightness at the object.

  • the eyewear 110 can also be disposed to maintain a record of lamp settings, so as to avoid any need to recompute those lamp settings when the user switches viewpoint between or among multiple objects.
  • the eyewear 110 can be disposed to receive user input indicating which objects are of interest to the user and which objects have simply caught the user’s attention for a short time span.
  • the eyewear 110 can be disposed to maintain bookmarks of which objects are of more than passing interest to the user, and to return to those bookmarks for use in determining lamp settings when the user’s gaze direction returns to those objects (or to near those objects).
  • the eyewear 110 can include (optional) light sensors disposed to respond to one or more of: an amount of luminance in an ambient environment, an amount of luminance from a specific light source, an amount of luminance from an object being focused upon by a user or in a background of such an object, or as otherwise described herein.
  • multiple such sensors can be disposed in the eyewear, as in one or more of: forward-pointing, downward-pointing, sideways-pointing, or as otherwise described herein.

  • a location disposed to receive light can be coupled to a light pipe, such as a fiber optic pathway, which is coupled to the actual sensor. This can have the effect that the location on the eyewear no where the light is received (thus, at a surface or similar location thereof), can be substantially different from the location where the received light is actually measured (thus, where the sensor is actually located).
  • the location on the eyewear where the light is received can be shielded against stray light, so as to assure that the luminance measured by the sensor is accurate.
  • the location where the light is received can include two measurement points and coupled to a comparator to process the different values, so as to identify stray light and account therefor.
  • one or more of the sensors can be disposed to measure luminance at a selected frequency or range of frequencies, such as only measuring light in a 500- 56onm range (green light), only measuring blue/ultraviolet light, only measuring red/ amber light, or some combination or conjunction thereof (such as red and blue, but not green).
  • a first sensor can be disposed to measure a first selected set of frequencies
  • a second sensor can be disposed to measure a second selected set of frequencies
