The way to roll your eyes is simple. Close your eyes. First, gently scrape your eyes ten times with your left and right hands, and then continue to close your eyes. Slowly turn your eyes clockwise for a dozen times, pause for a while, and then turn them counterclockwise for a dozen times.
Turning your eyes slowly is just like doing eye exercises, but the time should not be too long, just for half a minute to one minute at a time.
