There are some sites that cover the world of eyeglasses and related ocular devices, and then there is the site maintained by retired ophthalmologist Dr. David Fleishman. On his site, Fleishman brings together spectacle-related material about art, history and collecting all in one place. First-time visitors should stop by the "Introduction & News" area to learn about the overall scope of the site and to find out about the site's layout and organization. The "History & References" section is quite splendid, as visitors can read a developmental history of spectacles here, take in a recommended reading list, and translations of key historical documents related to spectacles, including the Sforza Letter of 1462. Visitors should not miss the "Interesting Topics" section, which includes features on famous religious leaders and their spectacles, representative examples of vision aids, and persons associated with the creation of new ocular devices, such as Benjamin Franklin and Dr. J. William Rosenthal.
