Yes. Without reservation.
While many modern texts have beautiful color diagrams and video supplements, none have the mathematical rigor of Jalie. When you sit for the ABO Advanced Certification or the UK’s FBDO exams, the questions are written using Jalie’s logic. ophthalmic lenses and dispensing mo jalie pdf
