senior systems administrator

Rochester Optical

<div>Rochester Optical was established in Rochester, New York in 1932. At the time, the owner saw a growing need for protective tactical eyewear for the Armed Forces, aircraft pilots, and police officers. Later, Rochester Optical became one of the country's few military prescription glasses frame manufacturers and supplied the Army and the Air Force with combat-ready ballistic eyewear for soldiers. After WWII, the tactical eyewear company expanded its services to include creating and selling prescription eyeglasses for the public. Rochester Optical quickly became one of the best glass frames and prescription eyeglass manufacturers in the area, producing many popular glass frame styles of the time with polarized tints.
Since then, Rochester Optical has added a large, full-functioning optical lab, a wholesale business line, and a stock lens facility and created wearable device solutions using augmented reality technology.
Rochester Optical is an optical leader and innovator in the eyewear space. Our headquarters are in Rochester, NY, and we continue to expand our national and international reach.
