Designing custom three-dimensional printed eyeglasses for children with frontonasal abnormalities: addressing challenges in access and fit.

Improving access to comfortable and well-fitting glasses for children with craniofacial differences may improve their visual outcomes. The purpose of this study was to describe challenges in spectacle fitting facing patients with frontonasal dysplasia and to report successful methods for creating custom 3D designed glasses. Additionally, the process of systematically collecting and analyzing spectacle-fitting challenges can inform future processes of automated design of 3D printed glasses and can be applied to other specific craniofacial syndromes.
