Tobii Eye Tracking devices are using near-infrared illumination to create reflections on the eyes that can be tracked with high accuracy. Near-infrared light can be found in our natural environment, for instance in candle lights, fires, and in the sun where the IR light is invisible or viewed as white light.
Since 2009 there is a new European standard called EN 62471 for products using LED lights. All Tobii Eye Trackers have been tested and approved by certified labs according to the European standard for optical radiation hazards of different lamps and lamp systems, IEC/EN 62471. Light emission that meets this standard is not harmful to the human eye.

Please use the following safety guidelines for your personal safety.
WARNING: Epilepsy warning
Some people with Photosensitive Epilepsy are susceptible to epileptic seizures or loss of consciousness when exposed to certain flashing lights or light patterns in everyday life. This may happen even if the person has no medical history of epilepsy or has never had any epileptic seizures. A person with Photosensitive Epilepsy would also be likely to have problems with TV screens, some arcade games, and flickering fluorescent bulbs. Such people may have a seizure while watching certain images or patterns on a monitor, or even when exposed to the light sources of an eye tracker. It is estimated that about 3-5% of people with epilepsy have this type of Photosensitive Epilepsy. Many people with Photosensitive Epilepsy experience an "aura" or feel odd sensations before the seizure occurs. If you feel odd during use, move your eyes away from the eye tracker.
WARNING: Infrared warning
When activated, the Tobii Eye Tracker emits pulsed infrared (IR) light. Certain medical devices are susceptible to disturbance by IR light and/or radiation. Do not use the Tobii Eye Tracker when in the vicinity of such susceptible medical devices as their accuracy or proper functionality may be affected.
WARNING: Child safety
The Tobii Eye Tracker is an advanced computer system and electronic device. It is composed of numerous separate assembled parts. These parts may get separated from the device, and may pose danger or choking hazard, when handled by children.
