The 9th Asia-Pacific Conference on Vision (APCV 2013) will be held on July 5th-8th, 2013 in Suzhou, China, a beautiful and historical city near Shanghai. APCV is an annual event attended by vision scientists from the Asia-Pacific region, as well as from other parts of the world. Following the successful APCV 2012 in Incheon, Korea, the Chinese vision science community will host the 2013 conference. Besides the regular talk and poster sessions, we have invited world-renowned vision scientists to give plenary speeches and special history talks during the four-day meeting. Eight symposiums covering diverse topics from retina to clinical vision to “The future of psychophysics” are also being organized. We are working hard to provide a forum for colleagues from all over the world to meet and to make it a big and happy gathering. Suzhou, a city with a history of over 2500 years, is famous for its gardens, temples, foods, and local music and opera. The beautiful conference hotel, Garden Hotel, has very nice guest rooms, meeting facilities, and as the hotel name states, beautiful gardens. Better than that, the hotel, located in the center of the city, is surrounded by various restaurants, bars, and shops, and is within walking distance to two very famous ancient gardens. We will organize a night tour of Master of Nets Garden to sample the local music and opera while enjoying the beauty of the garden itself.
