The FDA is aware of laser pointer injuries involving military personnel

Given the name and appearances, the first obvious thought is that perhaps lightsabers consist of some kind of Laser Pointer 50000mW . However, this hypothesis is easy to rule out. Lasers don't have a fixed length, as you can determine using a simple laser pointer. Further, unless the light is somehow scattered, a laser is essentially invisible as it passes through the air. Neither of these characteristics describes a lightsaber.

A new form of Christmas lighting using lasers is being blamed for a number of laser sightings in the aviation industry, including an incident at Penticton Regional Airport earlier this week.RCMP were called to Penticton Regional Airport on Sunday evening, Dec. 13, after a pilot reported seeing a green laser light flash in the cockpit as he was about to land, Penticton RCMP media spokesperson Cpl. Don Wrigglesworth says.

It’s believed a new form of Christmas decoration known as the 'Star Shower' laser projector may be contributing to the problem.Wrigglesworth advises residents using Christmas decorations that project laser pointer Mini light to be aware of the overhead hazards and ensure the projectors are properly aimed.More information on the dangers of lasers and aviation can be found on the Federal Aviation Agency.

Handheld laser pointers are commonly used in lecture halls and are considered to be harmless and safe.1 However, Green laser 50mw can cause severe eye injury, as demonstrated by the case of a 15-year-old boy. The boy had ordered a handheld laser pointer with green light on the Internet to use as a toy for popping balloons from a distance and burning holes into paper cards and his sister's sneakers. The boy's life changed when he was playing with his laser pointer in front of a mirror to create a “ laser show,” during which the laser beam hit his eyes several times. He noticed immediate blurred vision in both of his eyes.

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.
Do not aim a laser at any reflective surface such as a mirror or any other shiny surfaces where the beam cannot be controlled.
Check the label of any laser pointer that you own. If it has a power greater than 5 mW, dispose of it safely according to local environmental protection guidelines.
In the event of injury, immediately consult your eye doctor. Keep in mind that laser eye injuries are likely to be painless.

What is your choice to get high level of accuracy and precision dot measurement at different working surfaces? You might first think of red laser pointer, however, this simple alkaline battery power supply is not workable for long term continuous dot aligning works. In various industrial dot measuring works, high brightness 650nm red laser diode module is always a very recommendation for users to get high quality dot aligning on all desired working surfaces. Within the lowest time consumption, alignment laser dot can easily reach any working surfaces, thus always instructing users to get most precise dot alignment efficiently.

When laser dot alignment is processed in various industrial work fields, such as laser marking machine, laser engraving machine and button positioning on garments, usually red laser diode module is always required with long term continuous dot aligning on required working surfaces. As a result, when users are making dot aligning, users can try to make very easy installation of this advanced laser dot alignment tool on laser marking or laser engraving machines. In continuous laser marking works, these industrial laser devices would have to work continuously.
