Ravers lose sight at Russian laser show
Wow, quite a story. Apparently these lasers were supposed to shoot into the sky, but because it was raining the set up tents and had the lasers reflect off them instead. The lasers were too powerful to be doing this, and it's caused many of the partiers to go blind.
Dozens of partygoers at an outdoor rave near Moscow last week have lost partial vision after a laser light show burned their retinas, Russian health officials said on Monday.
Moscow city health department officials confirmed 12 cases of laser-blindness at the Central Ophthalmological Clinic, and daily newspaper Kommersant said another 17 were registered at City Hospital 32 in the centre of the capital.
Attendees at the July 5 Aquamarine Open Air Festival in Kirzhach, 80 km (50 miles) northeast of Moscow, began seeking medical help days after the show, complaining of eye and vision problems, health officials told Reuters.
"They all have retinal burns, scarring is visible on them. Loss of vision in individual cases is as high as 80 percent, and regaining it is already impossible," Kommersant quoted a treating ophthalmologist as saying.
Attendees said heavy rains forced organisers to erect massive tents for the all-night dance party, and lasers that normally illuminate upwards into the sky were instead partially refracted into the ravers' eyes.
