Laser toys could make children blind, an expert has warned. Toys 'R' Us stocks laser toys in Hong Kong and they have been selling well. The store manager of the Tsim Sha Tsui branch would only confirm that certain laser products were on sale but would not comment on their safety or any plans to withdraw them. 'If the light in a laser is stared at long enough, serious burns to the back of the eye can result,' said Dr Tim Allen, president of the British Columbia Association of Optometrists in Canada. 'Lasers do not belong in the hands of children.' Dr Allen's warning comes after the Consumer Council warned more than a year ago that pranksters playing with miniature laser pointers ran the risk of blinding people. The warning came after a Consumer Council investigation launched after a driver nearly lost control of his vehicle when a laser was shone into his eyes. Damage to the retina can occur if a pointer is aimed at the eyes for as little as 10 seconds. But laser light directed at the eyes appears to affect people differently. Some feel no pain, while others experience a long-lasting burning sensation. There have been numerous incidents throughout Canada involving laser injuries. Last summer, a Vancouver policeman attending a robbery call was taken to hospital after a man playing with a laser pointer aimed it out of his apartment window into the officer's eyes. Originally created for boardroom and school presentations, the gadgets are now in demand by sci-fi fans. The laser pointers, often made as key chains or pens, create beams which can be seen as far as a kilometre away in total darkness. Most products carry only fine-print warnings.
