This practice involves washing the eyes with clean, lukewarm water whenever time permits.
This can be done when taking a wash or bath, making sure that no soap enters the eyes.
EYE TONING TECHNIQUES
Though not part of Chakshu dhauti, there are various other simple techniques to help bring the eyes into optimum condition. These are:
PALMING
Sit comfortably, close the eyes and face the sun.
Feel the heat of the sun warming the eyes.
Keep the eyes closed and vigorously rub the palms of both hands together until they are hot.
Place the palms over the closed eyes. Feel the warmth and energy entering the eyes.
Do this for a minute or so.
Repeat 2 or 3 times.
This practice helps to revitalize and relax the eyes.
DISTANT/NEAR VIEWING
Sit so that you can see the horizon or so that you can see far into the distance. Focus your eyes on the nose tip.
Then focus on an object in the far distance.
Focus on the nose tip again.
Repeat this as many times as possible, then close the eyes.
This practice is very useful for exercising the eye muscles, which brings about changes in the focal length of the lenses of the eyes.
