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 math, vertex distance fixes, and handling refractive errors. With straightforward examples and real clinic cases, you'll do precise calculations and confidently explain lens options.
