The continuing development of new types and applications of lasers has appeared to surpass the development of specific eye protection for these lasers. There are a variety of eye shields on the market, but few are specifically designed for laser protection.
Our purpose was to test a variety of eye shields by two parameters, light transmission and temperature rise, and to determine from these measurements the most protective shield for patients.
We tested four plastic shields, one metal shield, and two sets of tanning goggles for temperature rise and light transmission when irradiated with a beam from a flashlamp-pumped, pulsed-dye laser.
The temperature rise at the surface of the shield opposite the laser impacts was no more than 0.2 degree C in any case. White light was transmitted at significant levels through several of the shields, but yellow light transmittance was noted only through the green eye shield.
Our measurements indicate that all except the green shield appeared safe from transmission of the 585-nm radiant energy. However, the optimal laser eye shield, in our opinion, would be a composite of several different shields' characteristics.
新型激光及其应用的持续发展似乎已超过针对这些激光的特定眼部防护措施的发展。市场上有各种各样的眼罩,但专门为激光防护设计的却很少。
我们的目的是通过光透射率和温度升高这两个参数对多种眼罩进行测试,并根据这些测量结果确定对患者防护性最佳的眼罩。
我们测试了四种塑料眼罩、一种金属眼罩以及两组美黑护目镜,测量它们在接受闪光灯泵浦脉冲染料激光束照射时的温度升高情况和光透射率。
在任何情况下,眼罩表面与激光照射相对的一侧温度升高均不超过0.2摄氏度。有几种眼罩能透过显著强度的白光,但仅绿色眼罩能透过黄光。
我们的测量结果表明,除绿色眼罩外,其他眼罩似乎都能安全阻挡585纳米辐射能量的透射。然而,在我们看来,最佳的激光护目镜应综合几种不同眼罩的特性。
