Is Eye-Tracking physically harmful for the user?
No. The EyeMax contains Light Emitting Diodes that emit light in the near infrared (NIR) spectra. This type of IR light occurs naturally in sunlight and in light from incandescent lamps. There are several national and international organizations that provide guidelines for human exposure to optical radiation and recommend exposure limits for the eye and skin. The most prominent are the: American Conference of Governmental Industrial Hygienists (ACGIH)1-2 in North America and the International Commission for Non-Ionizing Radiation Protection (ICNIRP, 1997). In the European Union, there is an Optical Radiation Directive that employs the ICNIRP exposure limits in the workplace. Other organizations recommend product-safety emission limits (ANSI, 2005, 2000, 2007; CIE, 2002; CENELEC, 2002; IEC, 2007; CDRH, 1995). Currently, there are two sets of different types of product safety standards that apply to the use of lamps—including solid-state lamps (LED’s) worldwide. These are: • The CIE Lamp
