What will I learn?
The Lenses Course gives you a fast, practical path to mastering geometrical optics for real-world vision correction. You will review thin-lens fundamentals, sign conventions, and ray tracing, then apply them to spectacle design, diopter calculations, vertex distance adjustments, and refractive errors. Clear examples and clinical scenarios help you perform accurate calculations and explain lens choices with confidence.
