It doesn’t take long for a laser to damage your eye.

Laser Safety Glasses for 1W Blue LasersNor does the laser need to be high-powered. According to a December 11, 2011, report by Laser Pointer Safety, a hobbyist was using a 1W, 445nm blue laser pointer in conjunction with a fog machine to create a “liquid sky” effect. The pointer fell off the chair on which it was placed and the beam struck the hobbyist (for “about one second”) in his right eye.

The result was a dark red blur in the center of his right eye’s visual range. No pain was experienced, as the retina possesses no pain receptors, but the damage was done, and permanently so. Doctors informed him that he would always have a small off-center blind spot in the affected eye.

On March 14, 2012, more than three months after suffering the injury, the hobbyist reported his progress. “I still have the blind spot, and was effectively told by the ophthalmologist that it would probably be there the rest of my life.”

There is often a misconception that 1W 445nm lasers are too underpowered to cause retinal damage, or that such damage would require lengthy exposure. None of this is true. Any radiation exposure in the wavelength range of 400-500nm has the potential to inflict irreversible retinal damage. Normally, photoreceptors in the eye are temporarily damaged when hit by light, but recover after a brief time; this is the process that causes you to see an afterimage of the sun or a flash bulb after looking directly into these light sources. Eventually the afterimage fades as the photoreceptors regenerate. But blue light damages cells in the photoreceptors and prevent them from “resetting.”

Because of this risk, single-Watt 445nm lasers are classified as Class 4, and usage of them requires the wearing of laser safety glasses. Phillips Safety carries a selection of laser safety frames that are ideally suited to filter out blue light and protect your eyes from an accidental strike. Without such eye protection, use of even a single-watt blue laser pointer means you and those around you run the risk of retinal damage. And it’s a risk that has real-world consequences.
