the critical distance is if the left edge of the reflector glass is central to the position of the human nose & the nose of the aircraft, if it is then is the distance from the left edge of the reflector glass to the centre of the reflector glass the same distance as the human anatomy from the centre of the human nose to the centre of the right eye.
if yes to all the above then the right eye is in perfect line with the centre of the reflector glass thus reflector light and the brain will naturally merge the left/right eye image in the same manner to if you were to use a marker pen on a bit of clear glass to mark a X and with both eyes open were to position it in line
close the right eye, however with respect to the gun sight and the above there needs to be a narrow angle of view for the “reflective recticel” so it
cannot be seen at all by the left eye when the right eye is positioned correctly.
