CVS organizes a symposium in alternate years on a theme of current importance in vision research. These meetings, of which there have so far been 31 bring in about 20 authorities to speak on topics related to a theme of current interest. The last two were "Frontiers in Virtual Reality" (2018) and "The Future of Attention" (2016). Attendance numbers between 100 and 200. Evening sessions are devoted to general discussion of the issues raised by the day's talks. We may provide some travel fellowships to pre- and postdoctoral students from within the United States and abroad. Students and fellows are active in these meetings and benefit greatly from meeting and discussing vision with a wide range of scientists in vision and related disciplines.
