Post an image where you see some of these problems and maybe someone can help.

One suggestion is to restrict the radius range of the circle finding algorithm to a range that you expect the eyes to be.

You shouldn't have started a new discussion for this - you already added this follow up question to your original question so there was no need to start a new discussion. Anyway, since it's highly unlikely anyone will take the time to download that File Exchange submission, try to duplicate your error, debug it for you, possibly fix it for you, and then explain to you what went wrong, your best bet is to ask the author or learn how to use the debugger yourself.
