OpticBench Turns Opticianry Math Into Repetition

Field notes

OpticBench divides optical mathematics into calculators, worked guides, reference material, and generated practice problems rather than treating exam preparation as a single quiz. Its examples include minus-to-plus cylinder transposition, a +10.00 D lens moved from a 12 mm vertex distance, and ANSI axis-tolerance handling. The site states that calculations run locally in the browser and that practice progress remains on the device, while noting that the tool is not a substitute for professional judgment or a full opticianry course.
