That of control group, worn glasses before and after 1 month, 3 months, 6 months, 1 year were: 4.12±1.86, 4.09±1.38, 3.58±1.45, 3.84±1.41 and 4.23±2.01, respectivley. Worn glasses after 1 month,6 months, 1 years there were no statistically significant difference(<i>P</i>>0.05). Three months after worn glasses there was significant difference(<i>P</i><0.05). The two groups had no significant difference before(<i>P</i>>0.05). Wearing glasses after 1 month, 6 months, 12 months, the two groups had significant difference(<i>P</i><0.05); 3 months after worn glasses there was no statistically significant difference(<i>P</i>>0.05). Spherical equivalent, observation time was 1 year: experimental group spherical equivalent degrees increased by 0.38±0.35DS, the control group spherical equivalent degrees increased by 0.84±0.56DS, the two groups were statistically significant difference(<i>P</i><0.05).<p>CONCLUSION: Both groups could reduce the AC/A value. The experimental group than the control group was better and faster to improve the relationship between the adjustment and collection. The AC/A value was on the high side after myopic degree growth.
