Abstract
The demand for Visual Acuity tests is increasing because people spend too much time watching electronic displays. It is inconvenient for people to go to a hospital or professional Visual Acuity test center for a simple Visual Acuity test, so the Self-Visual Acuity test system was paying more attention at present. In this paper, a self-Visual Acuity Test System based on field-programmable gate arrays (FPGA) was proposed. The design is composed of the VGA display module, the digital tube display module, the 4 * 4 matrix key module, and the light-emitting diode(LED) indicator module. The VGA display module, the primary module of the design, could control various patterns of the letter ‘E’ displayed on the screen. The size and direction of the letter ‘E’ will be changed by pressing different remote control buttons. The self-Visual Acuity test system with lower cost and easy operation will help people’s eyesight protection.
