Ma Haihua said that usually mild macular burns can be restored, and the impact on vision laser pointer blue is required in patients with macular special circumstances after the burn test can be determined. Experts advise laser pointers to avoid highly irritating direct eye contact with light, flash light, also need attention. According to the current "Modern Express" is a story, a 9-year-old boy in Jiangsu while playing red laser pointer, out of curiosity, his right eye is for one Irradiated for a few seconds, resulting in permanent vision damage that causes many Castle parents to worry about. "Children on summer vacation, often play in collaboration with a small yard, occasionally they took a laser pointer to play, sometimes casually irradiation.

To see the eyes of Jiangsu children after being irradiated, really worried about the safety of the children's eyes hurt. "Just the fact that people who lives in Guangrao Street said to prevent the child's eyes was hurt, she has other parents stepped in to send their children into the hands of the laser pointer "Confiscation." "Chat with the children knowing that they are buying from a 3000mw laser pointer near the school canteen inside." Ms. Zhang told reporters.

Laser pointer in the end there are no relevant international standards? In this regard, the Qingdao Municipal Quality Supervision Bureau staff said that if the laser pointer is defined as a children's toy, then it must be mandatory 3C certification. If it is defined as other products then it needs to be precise. It is understood that China's national standard GB7247.1-2012 "Safety of Laser Equipment - Part 1: Equipment Classification, Requirements": Class 1, 1M, Class 2 according to the degree of damage from low to high, the laser products are divided into the following levels, 2M class, 3R class, 3B class, four classes and each class has a 2000mw laser pointer marking regulations. If the national standard GB 19865-2005 "electrical safety of toys" needs, toys laser should meet class 1 laser radiation power limits.

This laser pointer blue with extreme performance is simply unbelievable

The first thing I noticed when I was removing this blue laser pointer from its packaging was that it is surprisingly solid and heavy. I wasn't expecting it to be done this well. When it comes to installing batteries there is no scam involved. You flip the back of it and inside is a plastic battery tray. I've personally seen much cheaper wagons in other items I own and honestly, I have no quality issues with the wagon at all. The carriage has markings on both the positive and negative ends next to the arrow that shows you which to insert at the end first. There are two sources involved with this blue laser pointer, one inside towards the head and one on the cap. Both feathers are very strong, so much so it was difficult to put the cap back on.

The case is good quality, with O-ring seals and a black non-slip finish according to the photos. I don't have a way to test the power of its output, but it seems to do the trick. It is visibly cloudy, which in this case is a desirable property to indicate that the spectral output is sloping per specification. The only bad thing about this for me is the laser itself is sensitive to movement, the cartage (or whatever you want to call it) seems to keep the batteries from wobbling a lot. So the Burning Laser Pointers would flicker or not turn on at all when I shook it. I somehow fixed it by filling some foam on the floor just so the batteries move less, it helps to stop the flicker, but occasionally I would have to hit it to make the laser pointer turn on.
