False.
The eyeball is like a complicated and precise camera. After myopia, the eyeball will become longer, causing parallel light to focus in front of the retina. Therefore, one has to get close to reach the appropriate focal length so as to see clearly.
Rotating the eyeball can really rest the eyes and relieve asthenopia caused by long-term use of the eyes, but there is no way to shorten the length of the eyeball, and it is impossible to change the condition of myopia [unable to focus].
At present, the most effective and safe way to correct myopia is to wear glasses. Some people think that myopia will get deeper and deeper after wearing glasses, which is a very common misunderstanding. In fact, wearing glasses can not only make people see clearly, but also has a positive effect on relieving asthenopia and improving binocular vision function.
