HANDHELD SELF VISION TESTING APPARATUS AND VISION TESTING METHOD

摘要

Disclosed are a handheld self vision testing apparatus and vision testing method. The invention comprises a corneal curvature measurement module. The corneal curvature measurement module comprises a first light source for emitting a first light beam and a first image collector for collecting the image formed by the first light beam after said beam has been reflected by the cornea. The first image collector is movably provided in the corneal curvature measurement optical path of the corneal curvature measurement module. The corneal curvature measurement module also comprises a first motor for driving the first image collector to move along the corneal curvature measurement optical path so that the first image collector moves to the imaging position. The first motor is used to drive the first image collector to automatically focus, requiring no assistance from a second person to adjust the focus. The person whose vision is being checked may complete the vision test by oneself. The present invention enables the person whose vision is being checked to operate by oneself, thereby enabling easy vision checking and effectively making optometry systems miniaturized and portable.
