The eye pressure is fluctuating during a whole day. Usually, the top value will be appeared before you get up, and the lowest value is appeared in the afternoon. The eye pressure will be raised after the painstaking work, or labored breathing, or after the head bowing. If you want to lower your eye pressure, please drink a little water and take some exercise in a modest way. The eye pressure's fluctuating must be within the value of 5mmHg, or the eyes will suffer disease.
