These images of the anatomy of the eye are from a book titled The Cyclopedia Book of Plates dated 1809. I am not sure which Cyclopedia they are from. The Encyclopedia Britannica was in print at that time as was Ephraim Chamber's Cyclopedia.
Both prints are for sale on Ebay.A webpage with extensive reference to Ephraim Chamber's Cyclopedia.
University of Wisconsin digitized version of Chamber's Cyclopedia.
