Abstract

The invention provides a handheld optometer, which comprises an optometer body, a camera, a controller and a display screen, wherein the camera, the controller and the display screen are arranged on the optometer body; the controller is respectively connected with the camera and the display screen; the camera is used for acquiring an eye region image of the tested eye and sending the eye region image to the controller when the tested eye is positioned at a preset test position; the controller is used for judging whether the tested eye is a left eye or a right eye according to the eye region image, generating a judgment result, and sending the judgment result to the display screen, wherein the display screen displays the judgment result. The handheld optometer achieves the purpose of miniaturization, simple operation and convenient carrying.

Description

technical field [0001] The invention relates to the field of optical technology, in particular to a hand-held optometry instrument and an optometry method. Background technique [0002] Technological progress is a double-edged sword. Thanks to advances in technology, the human body is freer than ever. We have a faster speed. "Sitting on the ground and traveling 80,000 miles a day" is no longer a joking and humorous joke. The spaceship travels more than 80,000 miles a day; we can fly higher, "can reach the moon in nine days" ; We can go deeper, "go to the five oceans to catch turtles"; we can see farther, and the countless "clairvoyance" and "wind ears" on the Internet provide us with real-time information. [0003] However, also due to the progress of science and technology, the constraints on the human mind are unprecedentedly heavy. Human beings are freer, but not happier for it. [0004] Since the first group of humans came out of Africa, humans have started a history...
