Paper Abstract

We have considered the important functions for developing accommodation-assistance glasses which can assist eye focusing for aged person with presbyopia.We focused on keys to realize small and lightweight variable focusing lens and gaze distance detection. We devised new variable focusing lenses with control and gaze distance detection with a tunnel light path device. A prototype of glasses with devised elements was manufactured experimentally. From the result of trial use of them and experiments for evaluating characteristics,it was confirmed that proposed technologies were useful for realization of accommodation-assistance glasses.
