The present invention discloses an eye-protecting range finder comprising a distance measuring module, a timing module, a metric measuring module, a warning module, an input module, a processing module, A power module, a pulse detection module, a bio-resistance measurement module, a wireless transmission module, and a sheathed casing. The eye-protecting distance measuring device can measure the distance between the eye and the gaze, measure the eye time, detect the ambient illuminance, issue a warning under the premise that the eye setting is not met, the volume is light and easy to carry, and the weight of the device is stabilized. In addition, the eye-protecting rangefinder can be used to measure health-related information such as heartbeat and body fat.本新型揭露一種保護眼睛測距儀，該保護眼睛測距儀包含一測距模組、一計時模組、一照度量測模組、一警示模組、一輸入模組、一處理模組、一電力模組、一脈搏偵測模組、一生物電阻測量模組、一無線傳輸模組及一包覆外殼。該保護眼睛測距儀可測量眼睛與注視物的距離、計量用眼時間、偵測環境照度、在不符合一定用眼設定前提下發出警示、體積輕便易攜行，及穩定裝置重量。此外，該保護眼睛測距儀尚可以順帶量測一些與健康有關的資訊，比如心跳、體脂肪等。
