Manifest vs cycloplegic refraction
WebTypically, vision insurance covers refractions that are done to identify potential refractive errors, such as myopia, hyperopia, and presbyopia. Medicaid. Medicaid coverage varies by state. In some states, Medicaid provides vision coverage for the refraction. In other states, Medicaid only includes coverage for children.
