Vision screening system

Abstract

The invention provides a vision screening system. The vision screening system comprises a clamp plate, a filtering window, a hand-held terminal and an upper computer, wherein the clamp plate is vertical to the orthogonal direction of the linear polarization direction of the filtering window, the filtering window is fixed to the front of the hand-held terminal through a fastening rope, the hand-held terminal and the upper computer are in communication through the wireless network, and thus the rapid screening for the vision is realized. The vision screening system has the advantages that the operation is simple, the response is sensitive, the evaluation result is strong in reminding property, the cost is low, etc. For the vision screening system provided by the invention, the circular polarization 3D vision technology, the vision light screening technology and the internet intelligent interaction technology are combined, thus the on-line dynamic screening and correcting for vision are realized, the comprehensive state of the vision and corrected vision of a tested person can be rapidly evaluated, a convenient and simple measures is provided for vision protection and health care of the tested person, and the evaluation result can be used as a reference tool for daily nursing and self health care.

Description

Technical field [0001] The invention relates to a screening system, in particular to a vision screening system. Background technique [0002] At present, the eyesight examinations of glasses wearers are mostly performed in optical shops. The development of the industry is uneven, the quality of personnel is uneven, and the quality of services provided varies. In the statistics of the correction status of adult wearers, it is found that a large number of corrective glasses for wearers are found There are various problems, and it is difficult to intuitively observe. The wearer often has no obvious perception, or feels it but does not know that it is caused by poor correction, leading to potential hazards to eye health. How to help consumers easily judge whether their eyesight is healthy and whether the corrective glasses are suitable, avoid potential risks caused by poor correction, and discover the factors of abnormal vision through self-examination as soon as possible There has...
