    The test entails:

    1. Retina Protection Factor 20

      The Retina Protection Factor (RPF) is a factor (with a percentage between 0-100) which quantifies the partial reduction (not complete avoidance) of blue light exposure in a certain wavelength range. <br><br>

      TÜV Rheinland has tested this product in order to ascertain its performance in reducing the blue light which emits from a display product. At the same time, the impact on the display’s performance is minimized, ensuring good display quality, including color range and CCT.<br><br>

      TÜV Rheinland has defined a catalogue of tests, which establishes minimum standards for RPF according to the product and its intended use. The test catalogue is based on internationally applicable standards and standards in common use within the industry and exceeds these requirements.<br><br>

      The laboratory tests included measuring the level of retina protection based on the Spectral Weighting Factors for Blue-Light Hazard as published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) in 2013 and adopted by the American National Standard Institute (ANSI) in 2015. <br><br>

      The keyword "Retina Protection Factor" confirms that the product meets TÜV Rheinland's test criteria.
