Risk of eye and skin injuries from exposure to products containing lasers

Owing to invisible infrared laser beam emission to human eyes, 808nm infrared cross laser alignment always gets superior advantages of good direction, high strength confidentiality, good coherence, and good color. Once users are making cross line alignment under quite special working fields, such as military targeting or measurement works, energy cannot detect any infrared laser source.

At the same time, whatever kind of advanced infrared cross line measuring works, users should always pay high attention to laser safety. Human eyes can never capture any infrared laser beam, but produce direct infrared laser source to human eyes directly.

Whatever kind of output power 808nm infrared laser modules users are operating, it is always no kidding to make cross line measurement. Besides proper adjustment of cross line targeting direction, users should also try to wear proper 808nm infrared laser safety goggles so as to make sure of secured infrared laser radiation and reflections. After users are making proper adjustment of cross line targeting direction, this advanced infrared crosshair laser module just brings users quite satisfied cross aligning efficiently

FDA is reminding consumers about the risk of eye and skin injuries from exposure to products containing lasers. Although most toys with lasers are safe and comply with performance standards, some laser products such as hand-held laser pointers are being misused as toys. See FDA Safety Communication for Laser Pointer Safety video.

FDA regulations limit the visible light power of hand-held laser pointers to 5 milliwatts (mW). Even at the 5mW legal limit, a laser aimed directly into the eye can cause temporary flash blindness. This will not likely cause permanent injury, because most people have a protective reflexes such as looking away, blinking, or making other movements to protect the eyes. However, reflections of the laser beam from mirrors or metallic surfaces may not induce the protective reflex quickly enough to avoid injury. In addition, intentionally keeping your eyes open and staring into a 5 mW beam will cause eye injury.

BACKGROUND: Lasers that emit more than 5mW visible light power can cause irreversible eye injury of increasing severity as the power increases. High-powered laser pointers can irritate or even burn the skin. Although illegal and potentially dangerous, high-powered laser pointers are available on the Internet and in stores. FDA believes that many eye injuries from laser pointers go unreported. Nonetheless, the FDA is aware of laser pointer injuries involving military personnel, researchers, hobbyists and children. The FDA is aware of many child eye injuries caused when children play with laser pointers. See FDA Safety Communication for description of incident reports.

The FDA wants to make consumers aware that they should not buy these lasers for themselves or as gifts for others. FDA recommends the following:

Do NOT buy laser pointers for children or allow them to use them. These products are not toys.
Do NOT buy any laser pointer that emits more than 5 mW power and does not have the power printed somewhere on the pointer or its packaging. Hand-held laser pointers over 5 mW and those that are not properly labeled are illegal and potentially dangerous.
Never aim or shine a laser beam directly at any person, pet, vehicle, or aircraft. The startling effect and temporary flash-blinding from a bright beam of light can cause serious accidents.
