The Solar Face Shield is clinically tested to block out the sun and provide UV protection for your face. It does not provide a skintight barrier to keep germs from entering on the sides of your face. If someone were to cough directly in front of you it would essentially capture the droplets on the surface of the shield, so it does provide that protection from any liquids but is not meant to take the place of other CDC recommended measures. You should consult your physician for the protective measures they recommend you take. Here is a way to provide full-face sun protection, not use chemicals on your skin, mess up your make-up or worry about applying enough sunscreen or missing a spot. You can even wear the sun shield after applying sunscreen for double comfort that you are sun protected. It is often that people land on this page after searching "face shields".
