Far and near visual chart based on millimeter recording method and intelligent detection system

The invention provides a far and near visual chart based on a millimeter recording method and an intelligent detection system; sighting marks are notch sighting marks; and visual values corresponding to the sighting marks in the visual chart are recorded through the millimeter recording method, namely, the visual values corresponding to the sighting marks are equal to the millimeter value of the width of the notch of the sighting marks. The intelligent detection system is provided with a registration and filing module, a data storage module, an intelligent calibration module and a vision detection module. According to the invention, the sighting mark is designed by adopting the international general unit of 'millimeter'; the millimeter value of the notch width of the sighting mark is directly taken as the vision value for recording, so that the unification of vision records among countries is facilitated; the direct comparability of the vision value is improved; the academic exchange is facilitated; the visio
