Abstract: The turn of “modernising vision” that took place at the beginning of the 20th century stems from the profound changes of traditional visual concepts since the 19th century.It aims to liberate people from outdated visual habits.The essence of vision was to be understood not even primarily as mechanical reflection on the existing visible world,but in a fundamental way,as a culturally shaped and historically variable productive processing of perception data.Modern art tries to create a modern visual form through works of art itself,and works of art are defined as the means or tools to realize visual modernization.Artists try to express a new visual view with art——seeing is full of the flow of time,not just the realization of a clear visual order;seeing is not a fixed process of vision,but a more conscious and concentrated observation of the world.From Albrecht Dürers central-perspective to Paul Cézannes multi-perspectivity combining time and space,the latter emphasizes the participation and seeing process of the viewer,and the change of this seeing mode is also the change of the relationship between man and the world.The discussion of visual modernization is still of great significance today.

Key words: vision, modernization, seeing, perspective
