eye exercises
It is recommended that children do eye exercises during the break of live class. This can relieve eye fatigue and relax eyes. But please remember that when doing eye exercises, you must wash your hands and don't leave your nails too long to avoid scratching your eyes.
Green scene
Encourage children to look at the green scene outside the window and let their eyes relax and rest. Because of the short green wave, imaging in front of the retina helps to adjust relaxation and reduce eye fatigue. This can not only protect eyesight, but also benefit children's health.
