Optician Geir Sivertzen, the man behind Panto Glasses, earned his craft certificate in 1983, as his father did before him in 1956, by creating the Panto from scratch. This included technical drawings, soldering and manufacturing of the Panto model, starting with rolls of wire, and finally grinding the optical glasses by hand.
Panto glasses were the quintessential masculine eyewear of the 1950s and 1960s and they gained enormous popularity in the 1980s when everybody owned a pair. Since then the model disappeared from the market, until recently. The Panto is now considered an established modern classic.
