Color contrast sensitivity was measured in laser operators before and after laser use. After argon blue-green laser treatment sessions, sensitivity was reduced for colors lying along a tritan color-confusion line for several hours. This acute effect is due to specular "flash-backs" from the aiming beam off the surface of the contact lens. It is caused only by argon 488-nm light, when the aiming beam intensity is high. In addition, a correlation has been demonstrated between the number of years of laser experience and a chronic reduction in tritan color contrast sensitivity. It is suggested that repeated acute changes caused by the argon lasers may cause cumulative effects and produce a chronic threshold elevation. A simple method of eliminating the acute effect is documented.
在激光操作人员使用激光前后测量了颜色对比敏感度。在氩蓝绿激光治疗疗程后，沿蓝黄色混淆线的颜色敏感度会降低数小时。这种急性效应是由于瞄准光束从隐形眼镜表面产生的镜面“回闪”所致。当瞄准光束强度较高时，仅由氩488纳米光引起。此外，已证明激光使用年限与蓝黄色颜色对比敏感度的慢性降低之间存在相关性。有人认为，氩激光引起的反复急性变化可能会产生累积效应并导致慢性阈值升高。文中记录了一种消除急性效应的简单方法。
