The use of a variety of data elements inour modern life has been increasingly deepening more and more important, it'salways in the days of facing all kinds of questions all sorts of problems, sowe use the new invention and undoubtedly the appropriate main elements. In ourlaser laser protective glasses seems to be our favorite, with its convenient,useful features convenient in steady improvement of our life quality and lifequality, but we actually tell us of laser protective glasses laser thismaterial not only so, the laser is a very powerful double-edged sword, if theimproper use of we will form a serious damage to the extreme. Laser damage tothe human body is mainly the eyes, followed by the skin.
(1)damage to eyes and vision laser can burn biological arrangements, especiallyfor retinal burns. Because the laser beam can be integrated into a very smallspot on the retina through the refractive system of the eye itself, the lightenergy is highly concentrated and causes the burn. The laser radiation in theinfrared or microwave region can be absorbed by the iris or the crystal to formheat damage, which can cause iris inflammation and cataract. The laser isrelated to the factors such as tone wavelength, pulse width, gap time, beamenergy, incident angle, illumination arrangement characteristics. By shininglaser glasses, but a sudden glare, showing vision vague or appearing before thefixed shadow, and even loss of vision. Laser radiation damage to the retina ispainless, easily overlooked. For a long time often exposure to small doses anddiffuse reflection of the laser shine, workers usually do not find damage froma vision, sometimes there is usually neurasthenia, visual fatigue after work,eye pain, no special performance. Laser pair of eyes of accidental damage, inaddition to individual attack permanent visual loss, most after treatment havedifferent degrees of rehabilitation.
(2)on the skin damage to the skin laser showed mild erythema, burning processuntil the arrangement of carbonization necrosis, may also lead to damage ofpigment cells, capillary embolism, sometimes visible stains and broken bloodvessels hemorrhage. Skin damage is usually reversible and reversible. The mainway to prevent laser hazard is safety education, strictly prohibited naked eyeviewing of the laser beam, pay attention to operation procedures; determine theoperating area and the risk zone and have eye-catching signs, unrelated personsare not allowed to enter, to wear suitable protective glasses, protectivegloves, timing check body, especially the eyes.
Laser, laser equipment has the pertinenceand usefulness is a day in the US is not ignored, and more important is thequestion of special laser and targeted can help us solve very many days, weshould use a laser with a clear know more is there a good a good laserlongitudinal always have side effects, if we have questions in the use of lasermaterial in the process of the formation of a very simple, since severe damage,and this damage is not timely rehabilitation can wear protective glasses fromthe appropriate laser maintenance major..
