[0021] According to the first embodiment of the present invention, a method for automatically prompting the distance between the human eye and the screen, such as figure 1 Including: A. Collect the user's image through the camera and preprocess the image. The preprocessing includes denoising and enhancing the image to improve the recognition rate of the face and eyeball pair. Image; B. Process the collected images, including locating the face through the face detection model; locate the eyeball pair through the eyeball detection model and find the user’s image eye distance r. The eyeball pair is the pair of eyes, By locating the position of the eyeball pair, the existing detection of a single eye is improved to first determine a pair of eyes and then measure the eye distance, which reduces the false detection rate, improves the recognition and improves the efficiency; the user’s age is calculated by the age recognition unit and based on The user’s age outputs the user’s eye dist...
