Let's slander laser on the human body and said we have seen too much too much, we are often in the news on TV to see similar briefing. Today, Laser safety glasses operators to share with you what the laser in the end howto cause harm to our eyes, then let's look at the specific meaning of it.
The laser on the human eye damage is the most important to unwarranted. People's eyes is like a very fine film on the human body, the human body from the outside world to get the information from the 70% eyes. And the damage to the eyes of the laser can be a function of all the eyes of the whole. There are three types of laser damage to the eye: shock effect, thermaleffect and radiation effect. Laser span instead, on the eyeball effect level on the contrary, antecedents are contrary.
The span of laser in the visible and near infrared range, refractive medium attracting rate is low, high transmittance, and the refractive focusing power (i.e. poly strong power). The intensity of visible light or near infraredlight into the eye can be through the human refractive media, accumulated in the retina. At this point on the retina laser energy density and power density will spread to many thousands or even the most number of times, a largenumber of light in an instant poly omentum on heat induced retinal photoreceptor cell layer increased rapidly, even in the photoreceptor cell degeneration and necrosis, solidification and lose sensitive effect. Protein coagulation degeneration to photoreceptor cell when the laser focus is not to overheat and cause reverse damage, once the damage will never cause blindness.
The harm to the eyes of the far infrared laser to the cornea, so this kind of laser span almost every was corneal attraction, corneal damage and most patients often thought the eye foreign body stimulation, be afraid of light, like tears, eyesight rise. Produce far infrared damage should cover eye injury, prevent contamination of the generation, to solve the disease. UV lasereye damage the cornea and lens is important. The laser with UV laser is located 0.38um~0.42um can make long eyesight increased significantly, so the crystalline grasp strongly attracted the band. At the end of the moderate withstandradiation, can cause cataract. 0.10um~0.28um and 0.28um~0.31um ultraviolet laseris of cornea and conjunctival attraction, can lead to keratitis, corneal epithelium and conjunctiviti, may also produce similar effects and blindness. In addition, blue light and so also may lead to macular degeneration.
On the other is the operation of the laser goggles for all of us, for the laser light on how to make our eyes mean. We expect everyone to see after the support, then we want to know more about the laser related to the above common sense. Please pay more attention to us.
