1. A method of measuring a refractive error using a reflection image of a pupil for a visible ray, the method comprising:
obtaining an image by projecting a visible ray, using a flash, onto a retina of a subject and capturing, using a smartphone camera, a shape and location of the image reflected in the pupil of the subject;
applying the image to a residual neural network (ResNet) model trained using data of an ImageNet based on clinical information into which result values of a refractive error of the subjects have been incorporated; and
outputting the refractive error of the image and a measurement factor measured to determine the refractive error based on the shape and the location reflected in the pupil in a process of deriving the refractive error of the image.
