If I have understood you correctly, I would guess the answer to your question would be that using a face shield does not appear to reduce the spread of COVID-19 in a major way.  There is some epidemiological evidence that face shields reduce transmission of disease, but this is not conclusive, and would be likely very hard to test.  Nevertheless, from an ethical perspective, I would suggest that you might look more deeply into the ethics of using face shields.  People are often uncomfortable with this idea, but it is important to consider the ethics of this action and how it relates to your personal belief systems and values.

so you're saying either I wear a face shield or not it will not help me to avoid the covid-19?

From my reading and experience, it is my understanding that the CDC, WHO, and health agencies do not recommend that people wear face shields.  Please be cautious though, as many different actions could help you avoid being infected by COVID-19.  I'm just saying face shields have not been found to be effective as far as I'm aware.
