Validation of modeling and simulation of virtual try-on of wearable device

Systems and methods for validation of modeling and simulation systems that provide for the virtual try-on of wearable devices, such as glasses, by a user, and for the virtual fitting of selected wearable devices for the user. Wearable fit measurements, display fit measurements, ophthalmic fit measurements and other such measurements associated with the fit and function of the wearable device may be detected from image data capturing the wearable device worn by the user. The detected measurements may be compared to corresponding measurements detected in a virtual simulation of the wearable device worn by the user. The comparison may provide for validation and increased accuracy/realism of the modeling and simulation systems.
