The study of examination of refractive errors of visual brain wave method of patients with language disorder

This paper studies the design of the novel optometrical examination of single pole brainwave system which measure visual brainwave signals of patients with expressive language disorder by single pole brainwave acquisition device, vision tester and software. The honeycomb pattern of Snellen test chart is an eye chart that can be used to measure the visual brainwave signals of the refractive error. This method used in myopic refractive correction is tested to 88% accuracy.
