    • A self-operated non-contact tonometer for measuring the intra-ocular pressure of an eye, projecting light into the eye and measuring the reflected light as affected by mechanical distortion. The cornea is distorted by delivering a pneumatic pulse. The tonometer consists mainly of an electro-optical unit mountable on the head of a user and a control unit. The control unit of the tonometer includes a display and optionally an audio device for instructing the user. The electro-optical unit employs a tubular wave guide, a light detector, and a reflector for deflecting a light beam to the eye and for eliminating a part of the reflected light reaching the detector. The aligning of the tonometer with the head of the user is optionally assisted by a reticle.
    • 一种用于测量眼睛的眼内压力的自我操作的非接触眼压计,将光投射到眼睛中并测量受机械变形影响的反射光。 通过递送气动脉冲使角膜变形。 眼压计主要由可安装在用户头部的电光单元和控制单元组成。 眼压计的控制单元包括显示器和可选地用于指示用户的音频装置。 电光单元采用管状波导,光检测器和用于将光束偏转到眼睛并用于消除到达检测器的一部分反射光的反射器。 眼压计与使用者头部的对准可选地由掩模版辅助。
