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.
