program in which Dr. Cohen trained nontraditional students in
Ophthalmic Dispensing Technology, including prescription eyeglass
assembly, were learning how to insert lenses into metal frames,
they were given study guides that outlined the materials to be
used and the basic tasks to be performed, and they were allowed
to perform those tasks at their own pace. Dr. Cohen did not
provide instruction in assembly techniques unless a student was
having difficulty completing the assembly.
While such result-oriented instruction may have been accept-
able in a setting such as the Cleveland Job Corps where the
participants were expected to assemble an optimum of 15 to 20
pairs of eyeglasses per week, B&L Ireland and B&L Hong Kong
trained their respective employees to use a standard technique
for sunglass assembly that the operators could repeat several
hundred times per day efficiently and correctly so as to result
in consistently producing quality sunglasses. Unlike prescrip-
tion eyeglasses that are assembled to fit a particular face and
for a specific prescription, sunglasses must be assembled to fit
a standard face. Consequently, there is a greater need for
consistent results with respect to the assembly of sunglasses
than with respect to the assembly of prescription eyeglasses.
The use of a standard technique for sunglass assembly allowed
operators at B&L Ireland and at B&L Hong Kong to achieve maximum
output of finished sunglasses that met B&L's quality standards
