1 December 1991 Interdependence of design, optical evaluation, and visual performance of ophthalmic lenses

The evolution of a new ophthalmic lens has a development cycle: design, manufacturing, optical evaluation, visual performance. At some point in this cycle a decision must be made to 'go to market.' Often this involves the manufacturing and optical evaluation (quality assurance) more than the design and visual performance aspects, although these latter contribute to the explanation of benefits which can be crucial to a technically innovative design. In this paper the manufacturing aspects of any specific designs will not be considered. However, the inter-relationship between the remaining three items are so strong that it is not possible to treat each one in isolation. In order to cover these relationships this paper will progress through 2.5 cycles starting with the design aspects.
