A better approach may be to hold manufacturers responsible for the products they produce.
As consumers we have the power to influence what manufacturers produce.
Local production began in 1961 with five manufacturers producing a total of 880 units per year.
As a result, few other manufacturers produced equipment compatible with the system.
The research might also help manufacturers produce needles less likely to chip or break.
Many manufacturers have produced lenses of this type under their own names.
Until recently, Americans appeared to be consuming more than the nation's manufacturers were producing.
But American manufacturers produced largely for the home market, and had little to fear from imports.
