Handheld Laser Pointer "Toys" Can Cause Serious Eye Injury


Handheld Laser Pointer "Toys" Can Cause Serious Eye Injury

A 15-year old boy ordered a handheld burning laser pointers online. He wanted it to pop balloons from a distance and play around with, this included burning holes into paper cards and his sister's shoes. Doctors from Lucerne Cantonal Hospital, Lucerne, Switzerland continue explaining in a letter published in the New England Journal of Medicine (NEJM) what happened when he used the laser pointer in front of a mirror.
http://www.lasereshop.com/images/p/hq01gn01651%20(3).jpg
The teenager wanted to create a "laser show" - he faced the mirror and zapped cheap high powered laser pointer beams in several directions. Some of the beams hit his eyes and his vision in both eyes blurred immediately. He did not tell his parents for fear of being told off or perhaps causing unnecessary alarm, and hoped the vision problems would go away.
http://www.lasereshop.com/images/water/hq01gn0096-200mw-13.jpg
Two weeks passed and his eyesight problems continued. The boy went to see a health care professional.
The ophthalmic assessment revealed that his eyesight had deteriorated so badly in his left eye that he could only count fingers on a hand at a distance of no more than 3 feet (about 1 meter); his right eye had 20/50 acuity.
An examination of the interior of the eye with an ophthalmoscope detected a dense subretinal hemorrhage in his left macula, there were also several "tiny round scars in the pigment epithelium of the foveolar region of his right eye". The clinician diagnosed bilateral retinal laser injury - injury to both eyes caused by laser beams.
Four months later the boy's eyesight improved, but there were still some problems and scarring.
Laser pointer 1000mw that were sold to the public used to have a maximum power of 5mW, which is not considered harmful for human eyesight. The handheld laser device the boy purchased on the internet was 150mW; 75 times more powerful.
http://www.lasereshop.com/images/p/1000mw-green-laser-pointer-hq010032-61946852s.jpg
Lasers which are powerful enough to damage human eyesight are generally used only by military personnel, and in such cases accidents and injuries are extremely uncommon.
Laser devices with a potential of up to 700 mW can be bought by anyone on the internet, the Swiss doctors inform. There are government restrictions, but this does not seem to stop these products being available online - they are presented as " green laser pointers ", like the ones lecturers use, and many look just like them.
http://www.lasereshop.com/images/p/hq01000301-05.jpg
These extremely powerful devices can cause serious and immediate eye injury. They are advertised as toys, even though they can cause blindness. Teenagers find them fascinating. There are even laser swords and other fun toys with powerful lasers installed inside them.
How is a child who is using one of these devices, and the other kids around him supposed to tell a harmless laser pointer from a dangerous one?the conclude that if the present state of affairs continues, there will be more such eye injurie.

About Laserpointer


Green laser pointers are fully legal for laser pointer use in most countries and at just below the maximum allowable legal power limit of 5mw for a pointer in most countries. We ensure that every high power green laser pointer is hand calibrated and tested to output at least 4.99mw and thus offers the expected stunning power expected of a real constant wave green (532nm) laser pointer, much brighter to look at than a regular red laser pointer and always with a visible green beam.
This high power green laser pointer will impress your coworkers, family and friends. Use it for your next presentation and everybody will know that you are ahead of the latest technology.
METAL BODY

This high power green laser pointer features a top precision all-metal body. Don't be fooled, some green laser pointers have a plastic body that is metalized. Our all-metal body green laser pointer is therefore robust and durable.

HIGH-QUALITY OPTICS

Our high power green laser pointer features an all-glass lens that focuses the beam to a sharper, rounder, clearer dot.

BRILLIANTLY BRIGHT

Powered by a Sony diode with a lifetime of 3000-5000 hours, it projects a high power green dot up to an incredible 2 miles away. And it so powerful that the beam itself can be seen for several hundred feet in darkness. That's why astronomers use it to point out constellations and stars in the night sky, the US Army uses it for training exercises, and executives at all levels use it to enhance their prestige. It's a very important tool if you get lost while hiking.

Are laser pointers dangerous?


It is always recommended that you avoid pointing a laser pointer at eyes because they can cause eye damage. The very strong laser pointers come with some dorky looking protective glasses and they come with these glasses come with the laser because they are dangerous.

Safety first when using a laser pointer


Although a laser pointer may not look it, they can be very dangerous. While they can be a very effective tool for drawing your audience's attention to things in your presentations, using them for other purposes can cause a lot of damage. Following a few simple safety tips will ensure that no one will get hurt while you're presenting.

- Never point your laser pointer at an other person, especially not the face. Just because a laser pointer may not be dangerous when pointed at the skin of another person it is still a good practice to never use it to point at people.

- Never look directly into the laser beam, even if you are sure that the strength of the laser is not high. Even a low powered beam can cause some damage to the eyes. Eye damage can be permanent so it shouldn't be treated lightly.

- Check for reflective surfaces before you present with a laser pointer. If the beam is reflected off an other surface such as a mirror or glass can be just as dangerous as pointing it directly into some one's eyes.

- There is something about a laser pointer that makes people act like children. I have been in many college lectures where a lecturer will use a laser pointer to make emphasis in class and students will ask to play with the pointer. Under no circumstance should you allow someone else to use your laser pointer, especially in a classroom full of people.

If you feel uneasy about using a laser pointer in your presentation you might want to look into using your computer mouse as a laser pointer. Microsoft powerpoint has a feature that will allow you to use the mouse pointer as a laser pointer on the screen. That by far will be the safest laser pointer.

My mouse works when it wants to.


It could be interference or distance from the receiver.
Try moving the receiver. Regular wireless mice can become unstable even at short distances.
