I got my first job programming computers in October 1966.
There were plenty of commercial design engineers using the computers around
me. By 1970, when I started doing NASA programming (to help keep me from
being drafted into the Vietnam war), there were more commercial design uses
of the computers around me than other uses. Ray tracing programs were very
common then; I remember in 1967 helping somebody use a CalComp plotter to
draw the output of ray tracing for a Fresnel design.
I think it's entirely possible that computers were used in leading-edge
commercial lens design in the early 1960s.
