Refresh Your Eyes

Vigorously rub your hands together to generate warmth. Close your eyes. Cup each hand and place them over your closed eyes.

Become aware of the play of light and darkness behind your eyes and watch it for a little while.  Slowly roll your eyes in clockwise circles- not straining in any way to do so.  Repeat using counter-clockwise circles, then let the eyes be still for a few minutes.

Slowly drop the hands, then softly open your eyes.  Notice ways your vision may appear to be refreshed.
