Silhouette eyeglasses lost, please help:

I was on a motorcycle ride Sunday 5/10/09 afternoon and had my Silhouette prescription eyeglasses in my pocket. The pocket was found later with nothing in it. I was riding around near Johnsburg and McHenry. These eyeglasses had a beaded croakie string around them in a grey case. These were 7560 6107 model marked on the ear. This is also had transition lenses and they were frameless with titanium ears and colored dark silver. If you found them I will make it worth while.
