Braille is a universal way to learn how to read and write, for the blind.[15] A refreshable braille display is an assistive learning device that can help such children in school.[16] Schools for the blind are a form of management, however the limitations of using studies done in such schools has been recognized. Children that are enrolled presently, usually, had developed blindness 5 or more years prior to enrollment, consequently not reflecting current possible causes.[17] About 66% of children with visual impairment also have one other disability (comorbidity), be it, intellectual disabilities, cerebral palsy,or hearing loss.[18] Eye care/screening for children within primary health care is important as catching ocular disease issues can lead to better outcomes.[19]
