Two ways to exercise the eyes where are the weakest part of our body and we can do it easily, any place and any time:
a/ close your eyes then open them widely.
b/ look up and down, look right and left.
c/ look around from right to left as the pin of the clock runs then look around from left to right.
d/ do repeatedly the above a/, b/ & c/ a few times.
a/ rub your both palms (hands) 36 times with force in order to have the warmth.
b/ place each of your palm (hand) onto each eye.
c/ do repeatedly a/ & b/ a few times.
I wish you and I have a good sight (a healthy pair of eyes) when we meet one day.
