Determining whether the glasses total block enough Public policy case studies and infrared light requires the use of spectrophotometertotal is a rather expensive piece of lab equipment. The organization warned against products claiming ISO certification or even citing the same number, but not tested by an accredited laboratory. Another problem was counterfeits of reputable vendors' products, some even claiming the company's name such as with American Paper Optics which published eclipse detailing the differences between its glasses and counterfeits.
