Three generations of innovation and collaboration
Haag-Streit International started in the city of Bern, Switzerland in 1858. The legacy of tradition and innovation began by combining the talents of two precision mechanics: F. Herman and H. Studer.
These clever entrepreneurs began their careers by manufacturing and supplying meteorologic measurement instruments to the observatory and weather station in St. Petersburg, Russia.
The next big break came when they realized the market for precision mechanics included ophthalmology. They began designing instruments with Dr. Hans Goldmann, who taught at the University of Bern.
 
It began with instruments for ophthalmologists
Together, the three men began creating precision instruments to aide examination techniques for ophthalmologists. These instrument designs remain the basis for instruments in use today.
By 1965, Haag-Streit International recognized a need to establish an American market subsidiary, and opened the first US office in New Jersey. In the early 70s, we acquired a supplier to better secure the high quality optics required for the integral slit lamp design and other mass-produced products.
To this day, the slit lamp manufactured by Haag-Streit International is considered the finest in the world.
