I worked in the retail with Varilux lenses in 1957-1958 the first timeOriginally Posted by drlenses
The the 2nd I saw was when we started to surface HOYA progressives in 1967-68 for the Canadian Market
The first progressive lens was designed by Oven Aves in 1907. I doubt he branded it though. Henry Gowlland patented improved progressive lens designs in 1909 and 1914. The first "modern" progressive lenses were Essel's original Varilux lens (around '59) and Univis's Omnifocal (around '61). The last progressive lenses will depend on the week you turn your assignment in. ;)
