I remember reading a while back that your eye is actually a big vector for getting viruses. We all touch surfaces and then touch our face and eyes a lot more than we realise.
Since COVID I wonder if these studies were reproduced.
We had a lot of talking point about why masks won't work were backed by these "people touch their face dozens of time every hour" kind of results, it felt completely absurd but there wasn't anyone going to redo them with strict control in the middle of a pandemic either. But now we could.
