What will I learn?
This Lenses Course offers a quick, hands-on route to mastering geometrical optics for everyday vision correction. You'll cover thin-lens basics, sign conventions, and ray tracing, then use them for spectacle design, diopter calculations, vertex distance corrections, and handling refractive errors. Practical examples and real-life cases build your skills in precise calculations and confident explanations of lens options.
