What will I learn?
This Lenses Course offers a quick, hands-on way to master geometrical optics for everyday vision correction. You'll go over thin-lens basics, sign rules, and ray tracing, then use them for spectacle design, diopter calculations, vertex distance changes, and fixing refractive errors. Simple examples and real clinic cases help you do spot-on calculations and confidently explain lens options.
