Safety regulations concerning the handling of low power lasers in the visible region (Class 2, according to DIN EN 60825-1) assume that the eye is protected by the eye-blink reflex, which should have completed within 250 ms during laser impact into the eye. A method has been developed to determine the temporal progression of the blink reflex by measuring the biosignal of the upper eyelid movement. In this procedure, which we call Electroblepharography (EBG), the electrical signal of the eyelid muscle is gained by means of self adherent electrode pads and is evaluated and charted after analog signal processing in the EBG-device. The graphical representation of the biopotential corresponds to the temporal position of the upper eyelid. Characteristic values as latency-time, position and velocity of the eyelid can be deduced.
关于在可见光区域处理低功率激光的安全规定（根据DIN EN 60825-1标准为2类）假定眼睛受眨眼反射保护，在激光照射眼睛期间，眨眼反射应在250毫秒内完成。已开发出一种通过测量上眼睑运动的生物信号来确定眨眼反射时间进程的方法。在这个我们称为眼睑电图（EBG）的过程中，通过自粘电极垫获取眼睑肌肉的电信号，并在EBG设备中进行模拟信号处理后进行评估和记录。生物电位的图形表示对应上眼睑的时间位置。可以推导出诸如潜伏期、眼睑位置和速度等特征值。
