As for the ways of improving visions without glasses, we have many alternatives.
The cause for bad vision is our bad habits in using eyes.
Sometimes, we are too rude to our eyes.
In fact, they are so fragile that they are in need of delicate care.
Among all the alternatives, palming is really a very natural method.
In fact, our eyes are moving at any time, even in our sleeping time.
This physiological process is automatically operated, for our eyes must maintain sufficient moisture.
Though this process can not be halted, we have some method to slow down it.
And this can help to relax our eyes.
First, mind relaxation is very essential for eyes.
Generally, our eyes will move with the paces of our minds.
That's to say, if we think wildly, our eyes will also move wildly, too.
Luckily, palming can help to slow down these rhythms.
A twenty or thirty minutes' palming can help you relax completely.
Before palming, we should rub our hands, so as to make them smooth and warm.
Later, palm two hands on eyes respectively.
However, palming is not touching.
The hands should cover eyes like cups, as no more pressure is needed.
Still, do not cause any stress.
We should put our elbows on something.
After that, we need complete relaxation.
With eyes closed, we should think that every muscle, in our bodies, from top to the toe, begins to relax.
Then, if we are completely relaxed, we can feel the deep darkness in our eyes.
For the first images in our eyes are grey in the beginning, and they become darker as we relax.
We should not think anything, forgetting everything that can bother us.
And what we should do is to see darkness of the images in our minds.
Thinking of some pleasant pictures can also help us to be more relaxed.
This process is suggested to last ten to twenty minutes.
After finishing the exercising, everything around will be much clearer as we open our eyes.
Objects will present themselves much nicer in color, shape, etc.
That proves our visions are improved.
