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].
