The present invention is directed to a system that may be incorporated into currently available electronic devices such as laptops, cell-phones and tablets, that help the user to maintain a viewing distance that is safe for the eyes. In order to avoid near-point stress on the eyes which may lead to the onset of myopia and/or accelerate the progression of myopia, especially in children or young adults, the system of the present invention monitors viewing distance and automatically distorts the image and/or text display into a format that is unreadable, for example, through blurring or pixilation, when the device is too close to the viewer. Alternatively, the system may automatically turn off the display when the device is too close and turn the display on when the device is at the proper viewing distance.本發明涉及可併入目前可用的電子裝置(諸如膝上型電腦、手機、及平板電腦)中的系統，該系統幫助使用者保持安全用眼的觀看距離。為了避免可導致近視初期及/或加速近視加深的近點應力，尤其是對兒童或年輕人而言，當裝置太靠近觀看者時，本發明的系統監測觀看距離，且例如通過模糊或像素化自動地將影像及/或文本顯示失真成不可讀的格式。替代地，當裝置太靠近時，系統可自動關閉顯示器，且當裝置處於適當的觀看距離時接通顯示器。
