Reading Glasses Testing

Most consumers choose a pair of reading glasses that not only improve their vision, but offer comfort and style as well. As a result, it’s imperative that brands, retailers and manufacturers ensure the reading glasses they make and sell meet the demands of consumers as well as the standards set forth by the industry. In addition, in the U.S. and EU, reading glasses are considered medical devices, requiring compliance with additional voluntary and mandatory standards. Intertek offers the following testing for both lenses and frames.
