Laser attack on goal keeper Vander could have gone into the eye
With the League play Panathinaikos Athens against Werder Bremen threatened champions on Wednesday of the arbitrators with an abort, because that had been dazzled of Bremen goal keeper Christian Vander repetitive with a laser pointer. This action was not only high-grade unsportlich, but for Vander also serious health consequences could.
Duesseldorf - laser gains straight in the eye medicine ever more significance. With laser beams opticians Netzhautkrankheiten can heal or treat defective visions. And one continues to work ever on new applications.
But laser has also its negative sides. With him one cannot only heal but also injure eyes with difficulty. Straight ones in the past months accumulate themselves the messages over purposeful attacks with laser pointers bespielsweise on pilots or completely up-to-date on the Keeper of Werder Bremen, Christian Vander. Peter Hering, director of the institute for laser medicine at the University of Duesseldorf, explained on-line” opposite “world: “The green laser pointers are ten times stronger than red and have a stronger glare than the sun.” With a Techno party in Russia several visitors suffered heavy eye injuries with a Lasershow. At the latest since then it might be certain that laser pointers are not toys. “Everyone, which deals with such an equipment, should be conscious the Gefahrenpotenzials, which assumes that, warns” stronghold Helbig, director of the university University of Regensburg. Therefore the professional association of the opticians guesses/advises to careful and responsible handling lasers.
Irreversible damage possible
“Laser light meets it the retina, can in simple cases to a glare of the sensory cells without structural damage come, which after minutes again “Helbig the first symptoms improves, explains. „Most humans know this phenomenon also from other bright sources of light.” In addition, during stronger or longer effect of the laser light on the retina an irreversible fabric damage could arise. “The described loss of seeing, how we know it after glare, does not regress again completely. This can lead to the lasting loss of central seeing and the read ability “, makes clear the expert. Laser beams proceed almost parallel from the source of light. Strong bundling makes high irradiancy possible, which can damage above all the retina of the eye.
Also light emitting diodes (LED), which ever more frequently for flashlights or than Fahrrad-Beleuchtung are used, can be perhaps just as dangerous for the eyes as laser beams. Also with them from there careful handling should be maintained. Both, LED and lasers, should be never directed toward the eyes. If a laser beam should meet nevertheless once in the eye, the eyes should be closed and the head from the jet be turned. Lasers and LED should be never regarded at the radiation source with magnifying glasses or other optical instruments.
Above all be valid it to avoid laser damage to the eye says refuge Helbig. „Visual disturbances after exposure of the eye with a laser arise if nevertheless, should visit one immediately an optician. He can try a treatment also highly proportioned Cortison, in order to keep the permanent damage as small as possible. “
