  • Visual acuity examination
    Patent number: 11246482
    Abstract: A vision screening apparatus conducts a photorefraction ocular screening test to generate refractive error data. Based on the refractive error data, a Snellen equivalent is determined. An evaluated person distance from the vision screening apparatus is also determined and used to generate an adjusted optotype size. The vision screening apparatus displays the optotype, adjusted for the Snellen equivalent and the evaluated person distance.
