This is best face shield I have found.

I did use it while unclogging a drain, to protect my face from splash-back, and found that the gap at the bottom is so large that I had to bend my neck at practically a 90 degree angle to actually protect my face, which wasn't very comfortable

This face mask is easy to use and stays on my head comfortably.

I liked the face shields I purchased because they are feather light, they don't distort my vision, they come in a set of two and I think that if I am careful in handling them they should last for quite a while

Protect the face from small debris
