All laser eye protection (LEP) should be tested to insure that it meets certain performance criteria. There are no American standard test methodologies other than military standards for LEP to meet performance criteria. Depending on the type of eyewear, the actual protection afforded during laser exposure may be different from the protection measured by standard methods. Specific user application environments may require additional tests for laser eyewear such as solar, temperature, and humidity stability. Optical quality testing methodologies including optical distortion, refractive power, prismatic deviation, haze, and chromaticity coordinate measurements are discussed along with the importance of user acceptance in optical quality, field-of-view, weight, comfort, corrective lens compatibility, and style.
