eno smart board.Does the use of electronic products in the education industry have an impact on students' vision? This is a topic of public concern. According to the principle of illumination, the electronic whiteboard relies on the projector to emit light onto the whiteboard, relying on the reflection of the whiteboard to let people see the content; while the interactive smart tablet uses the self-illuminating system, the light is brighter. At present, the internationally accepted saying is that in the case of sufficient external light, the light generated by self-illumination is more likely to cause eye fatigue than the reflected light. From a certain perspective, the use of interactive tablets is basically watching TV, which is why it is often subject to complaints from parents and even some young teachers. It can be seen that the advantages of electronic whiteboard in protecting students' vision can not be underestimated.
