title: Visual symptoms and compliance with spectacle wear in myopic children: double-masked comparison between progressive addition lenses and single vision lenses.
abstract: The aim of this study is to clarify visual symptoms and compliance with spectacle wear in children kusing progressive addition lenses (PALs). Ninety-two children, participating in a randomized, doublemasked, crossover trial to determine whether PALs reduce myopia progression (mean+/-SD age: 11.0+/-1.6 years; refractive errors: 3.11+/-1.34 D), wore PALs (1.50 D near addition) or single vision lenses (SVLs) for 18 months, alternately. A questionnaire survey was performed 6 and 12 months after the beginning of the use of the lenses (6-month survey), and the results were compared between PAL- and SVL-wearing periods. In the PAL-wearing period, the children reported difficulty in adapting to newly provided spectacles (36%), disturbances in distance vision (22%), vertigo in the lateral gaze (11%), and difficulty in ascending and descending stairs (9%). However, the frequency of these symptoms was not significantly different from that reported in the SVL-wearing period. There was no difference in compliance with spectacle wear between the PAL- and SVL-wearing periods, and 98% of the children wearing PALs reported excellent compliance. The results of this study indicate that, compared with SVLs, the PALs provide a similar level of comfort and compliance with spectacle wear for myopic children.
