WEDNESDAY, Sept. 8 (HealthDay News) -- A 15-year-old Swiss boy attempted to create his own laser show using a laser pointer he bought on the Internet and a mirror. Instead, he inadvertently beamed the laser into his eyes, creating permanent damage to his vision.
"These high-power laser products are very dangerous," said Dr. Martin Schmid, head of the retina unit in the department of ophthalmology at Lucerne Cantonal Hospital in Switzerland. Schmid is also one of the authors of the case report detailing the young boy's eye damage in a letter in the Sept. 9 issue of the New England Journal of Medicine.

Schmid said that part of the problem is that not all laser pointers are labeled properly, so it's not always easy to know if you have a pointer that could create serious damage. One sure way to know if you have a potentially dangerous laser pointer is if the laser can burn through paper, explained Schmid.
"Every laser pointer which is capable of burning holes into paper or of lighting matches or of popping balloons is highly dangerous for the eye and must not be used by non-professionals," he cautioned.
Those are exactly some of the uses the Swiss youngster was planning for his laser pointer. He told doctors that he purchased the laser pointer so that he could pop balloons from a distance, burn holes in paper cards and burn holes in his sister's sneakers.
While he was attempting his "laser light show," the teen said that the laser beam hit his eyes several times. Although he immediately noticed that his vision was blurry, he was afraid to tell his parents what had happened. He waited two weeks before letting them know that he was still experiencing blurred vision.
The vision in his left eye was so damaged that he couldn't count how many fingers a doctor was holding up until they were just three feet away. His visual acuity in his right eye was 20/50.
