ABSTRACT
For many years, first as a student and later as a senior researcher in the area of physiological optics, I have wanted a comprehensive resource for frequently arising questions. Although the situation in today’s Internet era is different than before, still I believe there is need for a reliable single source of encyclopedic knowledge. Finally, the dream of my youth-a handbook in visual optics-is a reality and in your hands (or on your screen). I hope this will help interested readers for a long time to come.
