Hi,
I just read about a nice eye tip which may be helpful to everybody in general. I must say that I am just expressing my opinion and it is one's personal choice to practice this activity. I do not endorse this in any way.
Now, I read about this is in a book on Ayurveda(Ancient Indian Medicine). It says that that in the morning, after freshening yourself and before eating anything, fill some fresh water in your mouth and then wash your eyes with fresh water about 40-50 times...then, throw the water out of your mouth.
You can also repeat this activity when your eyes feel tired.
