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: A sight apparatus is formed of a small housing having a curved top and an internally disposed chamber which is intended to be positioned generally at the location of a normal front sight as used with firearms intended for shooting remote targets. The housing incorporates a switchable light emitter such as an LED of substantial brightness which is positioned adjacent a small collimation chamber and exit aperture pointed parallel with the gun barrel axis toward the shooter's eye station. The brightness of this emitter output is selected with respect to the brightness of the ambient suround about the target so as to achieve enhanced brightness contour via physiological lateral inhibition within the shooter's eye. There then results a sharp sighting imagewhich represents gun tip positional data to the shooter. This data is available to the shooter even though both eyes are focused at the remote field of the target, generally at infinity, and defocused at the tip of the gun barrel.
