I have uploaded a new article on progressive lenses into the OptiBoard Download archive. This article was written by David Pope, a vision scientist at SOLA Optical, for the Optical Society of America. It will be published in their TOPS (Trends in Optics and Photonics) Volume 35, due out in September. (The article is generic in nature.) I'm sure David would love to hear any feedback about the article from those of you who read it and would like to post some comments.
