Abstract: A system for demonstrating an effect of opioid compounds to a user. The system includes an eyewear device including at least one lens having an overlay affixed to at least a portion of the at least one lens, the overlay including a pattern that at least partially obscures a peripheral region of the at least one lens, and the at least one lens including a plurality of independently-controllable regions configured to be switched between different levels of opacity; a processor in communication with the eyewear device; and a memory in communication with the processor having stored thereon a set of instructions which, when executed by the processor, cause the processor to: transmit a plurality of signals to the eyewear device to switch at least one of the plurality of independently-controllable regions of the lens between the different levels of opacity.

Abstract: Methods for simulating effects of impairment caused by recreational consumption of marijuana using a system including optical filters and various radiant objects. The system includes i) an optical filter having a pre-defined spectral pass-band and a non-diffractive spatial pattern configured to deviate a beam of light incident onto the filter, and, optionally, ii) radiant objects at least one of which delivers light in a spectral band corresponding to color that is complementary to the color defined by the pass-band of the optical filter. Method for demonstration and analysis of impairment of cognitive function caused by using the system to affect the vision of the user.

Abstract: A peripheral vision reducing apparatus for simulating a visual effect of intoxication is disclosed. The apparatus has at least one aperture configured to be disposed in the middle of a wearer's visual field. The aperture is also configured to permit a first amount of light to pass therethrough. The apparatus further comprises at least one filter surrounding the at least one aperture. The at least one filter is configured to be disposed at the periphery of a wearer's visual field. The at least one filter is also configured to permit a second amount of light to pass therethrough, and the second amount of light is less than the first amount of light.

Abstract: The present invention provides a viewing apparatus for simulating visual impairment. In one embodiment, the apparatus includes a frame defining a viewing area and first and second lenses supported by the frame. The first lens is disposed in a first region of the viewing area. The second lens is disposed in at least a second region of the viewing area. The first and second lenses have different image distortion patterns. In another embodiment, the apparatus may include frame and a lens supported by the frame. The lens includes a first plurality of image distorting features disposed in a first region of the lens; and a second plurality of image distorting features defined in the first region of the lens.
