The question of masks

I would put forward a hypothesis that masks will not change any statistics with a general population. China is a fine example. Studies have been done with an uncovered cough, but who does that? Covid comes in through the eyes, so that masking would have to reduce air viruses to zero.
In the mass wearing of masks, people wear them for hours and talk loudly to compensate. The electric charge on the mask fibers is instantly killed by moisture.
Masks work for a short duration in an OR, where everybody talks quietly. I would propose physics tests on particles, and would further check the effectiveness of wrap-around glasses for a significant effect on large numbers.
I am not arguing this, as it seems to be a matter of faith.
