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 portion 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 image which 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.

Sight apparatus for aiming a firearm at a remote target within a region exhibiting given ambient brightness, said firearm having a barrel extending along a central axis substantially from and parallel with a shooter\s eye position to a forwardly disposed tip, comprising: a sight housing mountable in the vicinity of said barrel tip, having an internally disposed chamber, and extending along a sight axis parallel with said central axis toward said eye position to a light exit aperture symmetrically disposed about said sight axis, of select principal cross sectional dimension, said housing having a curved upward surface extending to an opaque edge region of predetermined dimension surmounting said exit aperture said upward surface and said edge region providing a sight silhouette to said eye position; an emitter of light in the visual spectrum mounted within said sight housing chamber in an orientation for emitting light along and symmetrically about said sight axis, electrically energizable to generate a light output of predetermined brightness intensity in the visible spectrum, visually perceivable at said shooter eye position only as it is emitted through said exit aperture; and said exit aperture principal cross sectional dimension and said emitter predetermined brightness intensity being selected having a respective value and intensity level effective to evoke brightness contour by physiological lateral inhibition with respect to said ambient brightness at said shooter\s eye when focused upon said remote target.
