摘要：Protecting the eyesight has become one of the most current concerns in China, especially for the adolescent group. This design is a tool of protecting the eyesight for preventing the myopia. It is based on the ultrasonic sensor, photosensitive resistance, Bluetooth, the voice module and the smart telephone. It discusses the hardware design and software control for the eye sight protection. It uses CC2530 MCU as the core chip. Its circuit is to achieve the low-cost, high-precision, minimized eye sight protection. It is simple to operate. It includes the strong anti-jamming capability. Now the smart eye frame is heavy because of the battery. But it can supply power by the charger in order to reduce the weight. The initial survey shows more than 50% of students and parents lack the basic science knowledge for caring the vision. Therefore the design of a vision protector to protect eyesight is particularly important. The design of the hardware includes the circuit of the transmitter and the receiver in the ultrasonic, the alarm circuit, the circuit of detecting the light intensity, and Bluetooth communication circuit. The market has no similar products.
