Safety equipment is often an afterthought, but by the late 1800s increasing mechanization in all industries made safety equipment more necessary. Trades which had been performed by households or small groups using hand tools were now done by many people at greater speed with machines. This greatly increased the incidence of injuries and the motivation to reduce them. In the bricklaying, quarrying, stone masonry, tile, and foundry molding trades, common injuries were to eyes, lungs, hands, knees, feet, and from falls. Responding to demand, in the late 1800 businesses began to make safety goggles and dust masks. Later products included knee pads and steel-toed shoes.

The earliest reference I found to
stone cutter's safety goggles is 1886. These safety goggles had lenses made of mica (isinglass), which would not shatter like glass, and 360-degree side shields. Lenses had to be replaced frequently because of scratching. Early safety spectacles had thick glass lenses. Walter King of Julius King Optical Co. of Cleveland, Ohio,
developed tempered glass lenses in the 1910s. Other early US safety glasses manufacturers included American Optical, Bausch & Lomb, Duralite, NASO, and Willson.
Early protective gear also included bricklayer's finger tape and leather knee pads, both sold by Goldblatt Tool Co.
