Description

Technical field [0001] The invention relates to a vision testing device, in particular to a wireless vision testing device and method based on ZigBee. Background technique [0002] The myopia rate of adolescents in my country remains high, and with the improvement of academic qualifications, it has shown a trend of increasing year by year. The prevention and treatment of adolescents’ myopia has attracted more and more attention from students, parents and society. The traditional vision test method is time-consuming and laborious, and cannot be done by one person, cannot be tested every day, and cannot be found in time to see whether the vision has decreased. If there is a vision test method that can complete the test alone, it can be tested every day and give the latest vision changes Curve, then this method is bound to play an important role in myopia prevention. [0003] In recent years, wireless networks have developed rapidly, and various wireless network data transmission sta...
