“…3 However, programs in China, 3 Mexico, 6 and Africa 7 have reported poor compliance with free spectacles, with rates of observed, short-term wear at unannounced visits ranging from 13% to 41%. Factors limiting wear of glasses include discomfort or inconvenience, 6,8 concerns over being teased, 6,9 parental opposition, 6,10,11 lack of perceived need, 6,[8][9][10] and fear of damage to the eyes [8][9][10][11] (though a trial 4 has now demonstrated that spectacle wear is in fact protective against age-related declines in uncorrected visual acuity among children). Previous randomized trials of specially designed educational interventions promoting spectacle wear aimed at children, teachers, and parents have demonstrated very modest 3 or no 12 impact on observed use of glasses among children at unannounced follow-up visits.…”
