简要总结
Because of the characteristic of the glasses in this research through which violet light can penetrate, the glasses take effect only in outdoor environments where violet light exists, and not in indoor where there is little violet light. Hence, the period of outdoor activities is an important factor, and therefore, the primary and the secondary endpoints did not reach significant statistical difference.
