I kinda think you're getting a little too carried away with fear. Yes it's good to be cautious, but I am six months out from my TP. I think wearing eye protection isn't giving you much a d disinfecting your mail. While I wouldn't discourage from doing whatever you feel comfortable doing, I think keeping your distance is more important. Also find how many cases have been confirmed in your area. If there hasn't been many, decrease your concern a little. if there has been a lot, be more careful.
