Mass Customization in the Ophthalmic Lens Industry: Progressive Addition Lenses for Your Visual Map

Abstract

AbstractThe paper describes the Progressive Addition Lenses (PAL) personalization system obtained as a result of a joint R&D project conducted by Industrias de Optica, S.A. (INDO) and Institute of Biomechanics of Valencia (IBV). Traditionally, users have been asked to adapt to progressive lenses that are designed to fit an average wearer. INDO proposal is that a customized progressive lens that mimics the natural vision can be obtained by measuring the visual strategy of each individual user, defined as the coordination of eyes and head movements. The result is EyeMADE “made by your own eyes” and represents a major scientific advance and has positioned INDO at the head of the progressive lens field. The advantages of EyeMADE over conventional lenses are clear since it optimizes the visual comfort and allows for an easier adaptation process. A simple, robust and reliable system known as VisualMap DEVELOPER was developed in laboratory conditions to measure the visual strategy. Research showed that this simplified technique of measuring the visual strategy was equivalent to the more complex laboratory measurements. The individual visual strategy obtained with the VisualMap is then used by INDO to manufacture the personalized EyeMADE PAL using the latest ophthalmic lens technology using computer numerically controlled systems.
