Are there any health risks associated with this technology?
Some people wonder whether the light beams from the two light sources might damage their eyes, or perhaps even their skin.
The risk of such damage has been studied extensively, and is laid down in so-called safety standards. Compared to these standards, the light level from the ALPHA is very much below any safety limit. The green light sources may seem very bright, but they cannot damage your eyes; not even from a 1 cm distance. In fact, your eyes would not be damaged by 1,000 such light sources, even if you managed to place them at a 1 cm distance, all at the same time.
It should be clear that the skin, being much less susceptible to damage than the eyes, is also completely safe.
