Title:
SYSTEM FOR MEASURING POWER OF EYEGLASS LENS USING MOBILE DEVICE, METHOD THEREFORE, AND PROGRAM THEREFOR
Document Type and Number:
WIPO Patent Application WO/2016/076530
Kind Code:
A1
Abstract:
The present invention relates to a system for measuring the power of an eyeglass lens using a mobile device, a method therefor, and a program therefor. A method for measuring the power of a lens using a mobile device according to an embodiment of the present invention comprises the steps of: acquiring a first image by photographing a reference figure using the camera of the mobile device (S100); arranging the eyeglass lens between the mobile device and the reference figure and acquiring a second image by photographing the reference figure, which is seen through the eyeglass lens, using the camera (S200); comparing the first image and the second image, thereby calculating the magnification of the second image with regard to the first image (S300); performing a primary calculation regarding the power of the eyeglass lens on the basis of the calculated magnification and a predetermined curvature (S400); and grasping a curvature that is applied to a range, in which the primarily calculated power is included, and performing a secondary calculation regarding the power of the eyeglass lens on the basis of the curvature and the magnification (S500). According to the present invention, a user can easily measure the power of his/her own lens using a mobile device, such as a smartphone, and can order eyeglasses on line. Since there has been no method for measuring the eyeglass power, only eyeglass frames could have been circulated on line. However, adults undergo little change in eyesight, and do not have to measure the eyesight again, but have only to know the power of existing eyeglass lenses, when making new eyeglasses. Therefore, measurement of the power of eyeglass lenses that have been worn, according to the present invention, enables online circulation of eyeglasses equipped with lenses.
