Chakshu Dhauti (Chakshu = eyes and Dhauti =cleansing)
This is as simple as bathing your eyes. Make sure your eyes are open during the process. The washing needs to be done with clean water. Water used can be tepid, lukewarm or saline. In fact, the sure way of doing it is to do it with lukewarm water while bathing.
Eye Squeezing
Close your eyes and then simply squeeze it as tightly as possibly, hold it for few seconds and then release. This can help maintain the level of moisture in your eyes. Do 10 rounds of it every half an hour when in constant exposure to the screen.
Palming
Sit with your eyes closed and facing the sun. Try to mentally feel the warmth of the sun on your eyes. Press your palms firmly against each other, rub it vigorously for some time to create heat and then softly place your cupped palms over your closed eyes. You can also choose to open your eyes inside your palms. This practice relaxes your eyes and rejuvenates them at the same time. And yes, if you are not able to expose yourself to the sun, do it indoor.
Eye Clocking
Sit comfortably. Assume that your face is a wall clock. Lock your eyes in between your eye brows (this is 12 noon) as we do in Shambhavi Mudra; start moving your eyes clock wise as if you are looking at 1 o’clock, 2 o’clock and so on until you reach 12 noon in the middle of your eyebrows. Hence, 3 o’clock will be the corner of the left eye, 6 o’clock the chin which you will not be able to see directly, 9 o’clock the corner of the right eye. Now move in the opposite direction starting from 12 noon which is in between your eyebrows to 11 o’clock, 10 o’clock, 9 o’clock and so on until you reach 12 noon in the middle of your eye brows again. Repeat 2-3 times.
Distant and Near Viewing
Choose a place from where you can identify a definite object really far in the distance. Sit comfortably. Look at the tip of your nose – Agochari Mudra and then take your vision to the definite object that you had selected at the far away distance. Move back to the tip of the nose and then again to the object. Repeat 10 times and close your eyes to relax.
Diagonal Gazing
Diagonal gazing means looking at right upper corner followed by looking at left lower bottom corner and vice versa alternately. This gives good exercise to eye muscles.
Note: You might feel slight or shooting headache with some of the eye movements. It is only because your eyes are not used to those movements. Close your eyes for few seconds and you will be fine.
