The starting point of sight
In the11940s, some American gun mechanics began to manufacture guns with optical aiming devices. During the period of 1848, Morgan James of new york designed a tubular aiming device with the same length as the barrel. The second half of the device is equipped with a glass lens and two crosshairs for aiming. Later, similar aiming devices were used in the American Civil War.
But the sight with real practical value was born in 1904, which was developed by German carl zeiss and used in the First World War. World War II, the horizon began to mature.
