Refractive errors affect a larger proportion of the world’s population, regardless of age, ethnicity, or ethnic group. Globally, 2.3 billion individuals are known to have refractive errors, with (1.8) billion^. having access to^. appropriate eye_. exams and^. inexpensive corrections, and (500 million) have uncorrected errors that cause blindness or impaired vision (mostly in developing nations) [1]. They are a significant cause of poor vision and even blindness, if not corrected. However, they can be easily detected, measured, and corrected with spectacles and other refractive corrections [2]. An uncorrected refractive error has been identified as the leading cause of visual impairment in Asian school-aged populations [3-6] {Hispanic and European} [7,8].
