The focimeter is a necessary tool for any optician. It responds to the need to have stable reference samples that allow each optician to offer, on the one hand, optically excellent lenses and, on the other, to demonstrate the precision and reliability of the instrumentation in the event of disputes and complaints. The legislation currently…
