Mathematical Model for Enhancement of Visual Acuity through Electronic System Biofeedback

Abstract

The majority of people across the world have issues with their vision caused by human ocular refractive errors. Myopia affects 51% of adults, hyperopia affects 38% of adults, and astigmatism affects 27% of adults in the United States. This frequency is much higher in the adult population. 42 percent of global causes of visual impairment are attributable to failure to take prophylactic action against these disorders. This percentage includes presbyopia in adulthood. Visual strain brought on by an excessive use of electronic devices has led to the creation of new techniques and the development of various solutions, including corrective lenses, contact lenses, laser and non-laser refractive surgical operations, and so on. Using a signal electromyography feedback, we describe a technique that may be used to increase a person’s visual acuity. An electronic controlled lens with a power range of -10 to +10 diopters was used in its implementation, along with a LabVIEW interface-connected electromyographic signal gathering equipment. Five separate persons were given the Snellen test to evaluate the proposed system, giving each of them twenty opportunities to complete the exam. Consequently, it is feasible to enhance visual acuity up to 20/20 with an accuracy of 90 percent utilising a biofeedback system, together with other spherical ocular refraction errors such presbyopia, farsightedness, and myopia.
