Abstract

The invention discloses a method and device for detecting a dioper and a related system. The method comprises the steps that the light deflection angle of an observation pattern on a preset position on a screen and the opposite positions of the left part and the right part of the observation pattern are detected; according to the distances, which are equal, between two slits formed in an observation tube on the outer side of the screen and an optic axis of the observation tube, the ratio of the light deflection angle and the distances is calculated, and the ratio is the dioper; according to the positions of the two slits of the observation tube and the opposite positions of the left part and the right part of the observation pattern, positive and negative of the dioper are determined. According to the method, the complexity of using optometry equipment is simplified, the cost is lowered, and the accuracy and reliability of measurement are improved.

Description

technical field [0001] The invention relates to a method, device and related system for detecting diopter. Background technique [0002] When people use their eyes to observe nearby things, such as studying, using computers, mobile phones, etc., because the eyes need to focus on a shorter distance, the contraction of the ciliary muscle drives the curvature of the lens to increase, increasing the diopter of the eye. At this time, the increase in diopter belongs to the normal adjustment of the human eye. And after using the eyes. The eyes are in the rest recovery period, under normal circumstances, because the human eyes no longer need to continue to focus on the shorter working distance due to learning and work. The ciliary muscle will relax and drive the curvature of the lens to decrease, so that the overall diopter of the eye will return to the normal level within a short period of time (3 to 5 minutes), that is, the level when the diopter of the human eye is relaxed. ...
