Lenses Course
This course provides a practical foundation in geometrical optics, covering thin-lens principles, ray tracing, diopters, and spectacle design. Participants will apply these concepts to real-world prescriptions, vertex adjustments, refractive error corrections, troubleshooting, and effective patient communication in optical settings, building confidence in clinical calculations and lens recommendations.
