message=Poor distance vision is usually caused by near-point stress`n-------------------------------------------------------------------------------------------`nIn other words, staring at your computer screen for too long.`nSo flex your way to 20/20 vision. Every few hours, close your`neyes, tense your body, take a deep breath, and, after a few`nseconds, release your breath and muscles at the same time.`nTightening and releasing muscles such as the biceps and glutes`ncan trick involuntary muscles - like the eyes - into relaxing as`nwell. -- Anne Barber, O.D.
