Masks have some value to protect say the elderly making quick grocery store raids once a week or so.
Their effectiveness goes down as exposure time rises.

From my past knowledge of PPE (Personal Protective Equipment) it selection and limitations I can assure you that the masks that most people are wearing have almost no or no protective value for the wearer or those around them. For most they make it more likely that they will become ill not less, especially older folks.
I know two elderly people who became very ill this year from pneumonia... one of them died, the other has permanent lung damage. Both were habitual mask wearers. The heavy mask use was blamed in both cases for making each of them more vulnerable to catching pneumonia. It will eventually be confirmed that the masks killed far more people than they saved.
