A process for computer-assisted-design of an optical element allows for anticipation of errors that may arise in the actual manufacture of the element. A known optical design program is first operated to determine data representing the physical characteristics of the element that will provide a desired optical output. Then, the data representing the optimum physical characteristics are modified in accordance with a statistical distribution that represents the errors in the physical elements that are expected in the actual manufacture of the physical elements. The optical output is then determined for an optical element having the modified physical characteristics. This modified optical output is compared with the desired optical output to determine whether the designed optical element will produce the desired optical output when manufactured.
