Take the Emerald Test
Emerald is a four zone, reverse geometry alternative, using the Bausch + Lomb Vision Shaping Treatment VST process, that employs an empirical fitting philosophy. Diagnostic fitting is not necessary with this method where accurate keratometric and spectacle refraction measurements are all that is necessary for initial lens selection.
