Can I apply for a patent for myopia prevention and control training methods?

The relevant regulations stipulate as follows: if a claim only involves the rules and methods of intellectual activities, it should not be granted a patent right.

If a claim, except its subject name, defines all its contents as the rules and methods of intellectual activities, then the claim essentially only involves the rules and methods of intellectual activities and should not be granted a patent right.

For example: methods of teaching, teaching, training and taming animals; Rules and methods of various games and entertainment; Methods of physical exercise;

So if you only mean a training method, you shouldn't apply for a patent.
