Top Expert on this page
Expertise
I can answer almost any question about vision and general eye health care. As a non-surgeon, I may not be able to answer very involved technical questions about surgical procedures or highly specialized medical treatments. As of March 10, 2010, I will no longer answer any questions about Clear Care. People who do not understand how to use it should contact their eye doctor directly for advice.
Experience
I hold the degree of Doctor of Optometry and was in full-time private practice for twenty-five years. Currently I have reduced my schedule to part-time to allow time to write a book on another topic.
Organizations
American Optometric Association, Virginia Optometric Association, Northern Virginia Optometric Society (and others unrelated to this topic)
