Results 1) The subnormal vision of the experimental group had significantly reduced (P＜0.05),whereas the control group had no statistical significance;2) 17 of the cognitive entry of eye care knowledge in experimental group had improved,6 of the control group had obviously improved (P＜0.05);3) 6 of the eye behavior in the experimental group had improved,3 of the control group had obviously improved (P＜0.05). Conclusions The combination of medical education and health education curriculum is feasible.It can effectively improve the knowledge of children′s eye health care knowledge and the use of eye behavior,and can prevent and reduce the occurrence of low vision.
