This video provides a very simple exercise that you can use for getting rid of tension headaches and improving vision. At times our extraocular (eye) muscles can become tired and imbalanced, which can contribute towards tension, especially within the neck.
This video will help to prevent that from happening. Do this exercise for up to 1 minute a day, throughout the day.
