An eyeglass lens processing apparatus comprising: a processing chamber; a pair of lens chuck shafts (102R, 102L) which is disposed in the processing chamber and chucks an eyeglass lens; a lens rotating unit including a motor for rotating the lens chuck shafts; a processing tool which is disposed in the processing chamber and processes a periphery of the lens; an axis-to-axis distance changing unit including a motor for changing an axis-to-axis distance between a tool rotating shaft attached to the processing tool and the lens chuck shafts; a data input unit (2, 5) for inputting processing condition data including data on a target lens shape; and a processing controller which controls the lens rotating unit and the axis-to-axis changing unit to process the lens based on the input processing condition data; characterized by: a camera which is disposed in the processing chamber and is disposed outside the lens chuck shafts and has an angle of view where the camera can take a video picture of an operation of the lens processing by the processing tool; a memory which stores video pictures taken by the camera and the processing condition data input by the input unit; and a specifying unit which displays the video pictures taken by the camera on a display or transmits the video pictures taken by the camera to an external storage device by selectively reading out specified video picture and the processing condition data out of the video pictures and the processing condition data stored in the memory. a processing chamber; a pair of lens chuck shafts (102R, 102L) which is disposed in the processing chamber and chucks an eyeglass lens; a lens rotating unit including a motor for rotating the lens chuck shafts; a processing tool which is disposed in the processing chamber and processes a periphery of the lens; an axis-to-axis distance changing unit including a motor for changing an axis-to-axis distance between a tool rotating shaft attached to the processing tool and the lens chuck shafts; a data input unit (2, 5) for inputting processing condition data including data on a target lens shape; and a processing controller which controls the lens rotating unit and the axis-to-axis changing unit to process the lens based on the input processing condition data; characterized by: a camera which is disposed in the processing chamber and is disposed outside the lens chuck shafts and has an angle of view where the camera can take a video picture of an operation of the lens processing by the processing tool; a memory which stores video pictures taken by the camera and the processing condition data input by the input unit; and a specifying unit which displays the video pictures taken by the camera on a display or transmits the video pictures taken by the camera to an external storage device by selectively reading out specified video picture and the processing condition data out of the video pictures and the processing condition data stored in the memory. a camera which is disposed in the processing chamber and is disposed outside the lens chuck shafts and has an angle of view where the camera can take a video picture of an operation of the lens processing by the processing tool; a memory which stores video pictures taken by the camera and the processing condition data input by the input unit; and a specifying unit which displays the video pictures taken by the camera on a display or transmits the video pictures taken by the camera to an external storage device by selectively reading out specified video picture and the processing condition data out of the video pictures and the processing condition data stored in the memory.
