Forthe advantages of the laser we must know, but the laser protective glassesmanufacturer also said that is the advantage of more could not erase the harmof it, since it mainly produces is harm for our eyes and skin. So you will findin the work we will use a lot of protective gear.
Theharm of eyes and vision A laser can burn biological tissue, especially for themost common retinal burn. Because a laser beam can through the eyes ofrefractive system focused onto the retina into a very small spot, make thelight energy concentration and cause burns. In the infrared region or in themicrowave laser radiation can be absorbed by the iris or crystal thermaldamage, leading to iritis and cataract. Laser damage to eyes tone wavelength,pulse width and interval time, the beam energy and incident Angle, areaccording to the structure characteristics and other factors.
Glassesby the laser irradiation, but suddenly a sense of glare, blurred vision orfixed shadow emerge in front of him, and even loss of vision. Laser radiationdamage to the retina is painless, easy to be ignored by people. Long-termexposure to low doses of and diffuse reflection laser irradiation, the staff don'tusually found that damage to his vision, sometimes there are general debility,vision fatigue, sore eyes after work, no special symptoms.
Theaccident harm of laser to eyes, despite a permanent vision loss, most of allhave different degrees of recovery after treatment. Damage to the skin Laserprocess characterized by mild erythema of the skin damage, burn until thecarbonized necrosis, moreover also can damage the pigment cells, causingcapillary tied plug, sometimes visible blood vessels broken stains and spilledblood.
Skinlesions are usually reversible and can be complex. Prevention is the method ofthe main the laser safety education, it is forbidden to open hole to watch alaser beam, pay attention to the operation procedures; Determine the operatingarea and the dangerous zone and should have eye-catching warning signs,irrelevant personnel shall not enter, wear appropriate protective glasses,protective gloves, regularly check the body, especially the eyes.
Butthe laser protective glasses manufacturer think eyes are the most vulnerableparts of the body, we are also the most important part, so we must especiallypay attention to our eyes, choose to suit our safety glasses.
