This is the American Optometric Association's website. It has a wealth of information as well as a link to FAQ in Spanish.
This is the site sponsored by the California Optometric Association. It is also quite helpful with a few programs specific to California, such as the CVF, which provides eye exams and glasses to the working poor.
