Caution with the Danger of Green Laser Pointer

Laser research organization reveals that direct exposure to over 400mw high power green laser pointers can damage the human eye to some extent. Certainly, here I mean the green laser pointer rather than red laser pointers, coz the power of the former beam is much stronger.

It's not warning people of not using green laser pointers, but of using it safely, if not creatively(see how to use a green laser pointer creatively.

The study, published in the May issue of the journal Archives of Ophthalmology, found that exposures of just 60 seconds to over 400mw green laser pointers can cause visible harm to the eye's retina while as long as you don't point at the laser beam upon your eyes with the high powered green laser pointer, the self-healing power of naked eyes will "handle" it right.

The Mayo Clinic study was conducted by pointing a green laser pointer directly at the retina of a patient's eye. The eye was already scheduled for removal due to a malignancy.

The green laser caused damage to the pigment layer of the patient's retina, researchers report, but it didn't cause a measurable decrease to the eye's vision, so the Laserto.com hope most laser users can use it with caution, esp. when handling a over 400mw green laser pointer.

Certainly, the green lasers is impossible to be banned because it has been used for a variety of purposes, such as astronomical, medical, military, laboratory and other purposes, and high power green lasers also become the best option for those creative and daring spirts who never want to use a laser as a presentation pointer, a stargazer, or a cat toy, However, laser safety also can't be neglected. People have been at airports and shining them directly into the cockpits of planes and pilots eyes. It's reported that in 2007 a girl was caught by FBI by pointing at a airplane who was on duty. Later the innocent girl just said she was not deliberate playing with the 50mw green laser from Laserto.com. It caused a sensational controversy then, and certainly Laserto.com, a commercial laser business factory, can't be blamed coz they also advise any customer to use it with caution or to wear a laser safety goggle.

However, not all young laser lovers are as cautious as they expected, while longer exposures to green laser pointer s could cause vision damage, warned researcher and ophthalmologist Dr. Dennis Robertson in a prepared statement. Green laser pointers are widely available and sales aren't regulated, which means they can be bought by children. Class 3A green lasers are used by amateur astronomers to pinpoint objects in the night sky. They're also used in daylight by the construction industry and architecture educators to point out structural details. Of certainly, they never want it to be banned, otherwise it will cost them more money to purchase one from the other side in the Earth.

"Green lasers are not a public health hazard at this time, but something people should be aware of," Robertson said. "I'm raising concerns that people should be cautious when using green laser pointers not to point them at someone's eye or face. It's like how your use your knife - carefully."
