Abstract: Eyewear for use by a person exposed to an environment of glare-inducing illumination. The eyewear has a frontal portion for confronting the eyes, which frontal portion extends between an upper and lower periphery. A transparent optical region is provided within the frontal portion for intercepting lines of sight substantially above and below the slightly elevated standard line of sight at the mid-pupillary position of the eyes. For normalizing overhead and reflected glare to a level of diffuse illumination reducing veiling luminance and asthenopic effects, upper and lower translucent regions arc provided within the frontal portion. The upper translucent region extends substantially upwardly from between the standard line of sight and the upper periphery of the frontal portion. The lower translucent region extends substantially downwardly from between the standard line of sight and the lower periphery of the frontal portion.

Abstract: Apparatus for carrying out aircraft pilot training and proficiency procedures comprising goggles having selectively translucent regions adjusting sight distance through the windscreen of the aircraft while permitting unrestricted vision of cockpit instrumentation. The vision occluding regions may be provided as polymeric overlays having a translucency selected for varying visibility distances and which may be mounted upon the lens region of the goggles in removable fashion through the development of static electricity between the components.

Abstract: System, method and apparatus wherein eyewear is provided particularly suited for use in conjunction with luminescent displays such as visual display terminals and which serves to improve operator performance and reduce asthenopia. The eyewear includes a forward frame portion having a centrally disposed bridge section and right and left temple pieces extending from the frame portion. The frame supports a clear optical region dimensioned for intercepting lines of sight substantially only within the inferior field of view of the user's eyes and a translucent region intercepting and blocking lines of sight directed substantially outwardly from the mid pupillary position of the user's eyes within the superior field of view. Preferably, the clear optical region is pigmented to define an optical filter and this filter preferably is selected having a pigmentation in the yellow portion of the visible spectrum.
