A member of the Russian Academy of Sciences, Doctor of Biology Grant Demirchoglyan, says that like any unique optoelectronic system the human eye both receives and emits signals. The return radiation going from the eye is the short-wave one and thus can be as penetrating as X-rays or a laser. It may influence the central nervous system, the brain and the whole body in general. If experts tentatively prove that the power of human eyes is of the same nature as that of a laser, we will have to believe that fictitious characters able to burn a human being to ashes actually exist.
