The demarcation line varies relative to the orientation of the eyewear to present a visual depiction corresponding to a natural horizon. The eyewear includes at least lens assembly that has an interior cavity defined between an inner lens, an outer lens, and a sidewall defined to join the lenses around the periphery of the lens assembly. A volume of liquid is carried in the interior cavity. The volume if liquid is responsive to changes in the orientation of the eyewear relative to the horizon. ## Claims ### Claim 1 A motion sickness prevention eyewear, comprising: a frame adapted to be worn on the head of a user; at least one lens assembly mounted in the frame, the lens assembly having an inner lens and an outer lens disposed in a spaced apart relation by at least one sidewall defining an interior cavity within the lens assembly; and a volume of a liquid within the interior cavity to fill a lower portion of a field of view through the lens to present a demarcation line that varies with the orientation of the eyewear to correspond to a natural horizon line. ### Claim 2 (depends on 1) The motion sickness prevention eyewear of claim 1, wherein the liquid has a selected tint. ### Claim 3 (depends on 2) The motion sickness prevention eyewear of claim 2, wherein the selected tint corresponds to a predetermined environmental use. ### Claim 4 (depends on 2) The motion sickness prevention eyewear of claim 2, wherein a colorant provides the selected tint. ### Claim 5 (depends on 1) The motion sickness prevention eyewear of claim 1, wherein the at least one lens assembly includes a first lens assembly and a second lens assembly. ### Claim 6 (depends on 1) The motion sickness prevention eyewear of claim 1, wherein the sidewall is formed of a bonding agent. ### Claim 7 (depends on 6) The motion sickness prevention eyewear of claim 6, wherein the bonding agent is resiliently sealable when penetrated by an injection needle. ### Claim 8 (depends on 1) The motion sickness prevention eyewear of claim 1, wherein a remaining volume of the interior cavity includes an inert gas. ### Claim 9 (depends on 1) The motion sickness prevention eyewear of claim 1, wherein a vacuum is applied to the interior cavity. ### Claim 10 (depends on 1) The motion sickness prevention eyewear of claim 1, wherein the frame is an eyeglass frame. ### Claim 11 (depends on 1) The motion sickness prevention eyewear of claim 1, wherein the frame is a goggle. ### Claim 12 A motion sickness prevention eyewear, comprising: at least one lens assembly, the lens assembly having an inner lens and an outer lens disposed in a spaced apart relation by at least one sidewall defining an interior cavity within the lens assembly; and a volume of a liquid within the interior cavity to fill a lower portion of a field of view through the lens to present a demarcation line that varies with the orientation of the eyewear to correspond to a natural horizon line.
