The laser, which is a natural material weever invented and used the process of the greatest, application to us in almostall aspects of life can see examples of laser equipment data. We can say thatthe career facing laser because the laser has become better more brilliant. Butthe more time we enjoy in the laser equipment data bring us spend the same weenjoy the process of laser protective glasses manufacturers have reallyinvented most people know when a laser fresh side of brilliant and beautiful,bring irreparable damage in the us.
The acute damage to the eye when thevisible or near infrared laser power density is very low. The main reason isbecause the laser power density is low, the retinal structures althoughreceived laser photon energy is getting hot, but the heat on the one handthrough the process part of vibration transferred to the surrounding structure,and then spread to the surface of the eye; microvessel and on the other handcan heat to the clouds in the bottom of the retina choroid, followed by microthe circulation of the blood vessels in the eye and then distributed to gooutside. As to the whole eye, retinal temperature was not significantlyreduced, or a slight change in the range is still tepid, the eyes full ofharmful.
Retinal damage depends on the power andtime, such as when the power density of visible or near infrared lasercontinuously increasing, the heat induced retinal tired rate is greater thanthe heat dissipation rate, or power density is not very high, but received along time receiving retina, retinal photon beam spot temperature must bereduced, namely according to Yin more glitter long, temperature increasing,temperature increasing, temperature above 10 degrees across the abnormal eye,will cause retinal damage.
Faced with lasers, most of us now knowthat the most important of our lives is the most important of all, the mostimportant of all, the most important of all. Laser is a kind of the mostimportant materials in our life, and more important is not only the interestsof the laser, and laser harm, is not a simple double-edged sword, not good forour damage with the formation of irreversible and laser protective glasses canhope everyone may understand the application value of laser, laser the.
