CHICAGO (Nov. 10, 2014) – Prevent Blindness, the nation’s oldest volunteer eye health and safety organization, has announced that Andrew Alcorn, president and CEO of Block Vision, Dr. Chad Overman, director of professional relations – Health and Wellness US at Walmart, and Dr. R. Tracy Williams, executive director of the Spectrios Institute for Low Vision, have been elected to the Prevent Blindness Board of Directors.  The vote was held on November 8 at its 2014 Annual Board Meeting in Chicago.


Block Vision provides wellness vision and eye health benefits management services including eye examinations, corrective eyewear, primary eye care and comprehensive medical-surgical eye care management.

He later joined the corporate team as a regional talent specialist. Today, his duties are to provide overall direction and enhancement of Health and Wellness professional relations and strategic partnerships with industry stakeholders. Dr. Overman attended Iowa State University and received his Doctorate of Optometry from Southern College of Optometry in 1995.


Dr. Williams serves as the Executive Director of the Spectrios Institute for Low Vision in Wheaton, Ill.  The group provides a variety of services including clinical low vision examinations, counseling and teaching the skills of daily living using low vision aids and technology. He served as chair of the American Optometric Association Low Vision Rehabilitation Section from 2005-2007, co-chair of the National Eye Institute/National Eye Health Education Program Low Vision Subcommittee from 2002-2008 and has served as chair of the National Accreditation Council for Agencies Serving the Blind and Visually Impaired since 2008.  He is also the team eye doctor for the Chicago White Sox and the Chicago Bulls.


“Over the years, Prevent Blindness has had the great fortune of having some of the best and brightest leaders serve on our Board of Directors.  This year’s group of new members is no exception,” said Hugh R.
