Larry Alexander, OD FAAO (1947 - 2016)


My heart is broken hearing of Larry's passing. Anyone who knew Larry was a better person for it. Last week Larry asked me to remove EyeLessons in its entirety so I reluctantly took it down. He also told me I could do with it whatever I want with it, so I'm putting it back up so others can enjoy Larry's style of education for a little longer.  EyeLessons was a labor of love, and I was constantly amazed at the content output by one of Optometry's leading educators.

Larry, I will miss you. It was an honor working with you and calling you a friend.
