A Brief History of Red Dot Sights Red dot sights have become a popular choice among shooters in recent years, but their history dates back to the early 1900s. The first red dot sight was invented by Swedish optical engineer, Oscar Ziegenhagen, in 1900. His invention, called the "Zielgerät 1229", used a red dot projected onto a glass plate to provide a sighting system for anti-aircraft guns. In the 1970s, the technology behind red dot sights began to advance. The first commercial red dot sight was introduced by Aimpoint in 1975. Aimpoint's sight used a light-emitting diode (LED) to project the red dot onto a lens, making it more durable and efficient than previous models. In the 1980s, the U.S. military began to experiment with red dot sights for use in combat. The Trijicon ACOG (Advanced Combat Optical Gunsight) was developed in 1987 and became a popular choice among military personnel. Since then, red dot sights have continued to evolve and improve. They have become a common sight on rifles, shotguns, and handguns, and are used by hunters, competitive shooters, and military personnel around the world. Today, there are many different types of red dot sights available, each with its own unique features and advantages. Some are designed for use in specific situations, such as low light conditions or long-range shooting. Despite their relatively short history, red dot sights have become an essential tool for many shooters. With their accuracy, speed, and ease of use, they have revolutionized the way we aim and shoot.
