By the age of seven, in elementary school, at this time the pressure on children to learn increases, writing time also becomes very long, in reading or writing, after half an hour to 45 minutes must be a 10-minute break. The so-called 10-minute break here, not like most students: out of the room, said to rest, walk to the living room, talk a little, eyes also keep looking at the TV or other near objects, such a break can only be said to relax the brain, for the eyes, there is no rest to speak of. It should be like this: 10 minutes rest, stand up and walk a little is right, but the eyes should be looking away, it is best to walk around for 5 minutes, and then go to the window to look away for 5 minutes. Look far away is to look at objects more than 5 meters, more than 10 meters is better, so that more can relax the eye ciliary muscle, let the eyes rest.
