Not very comfortable but usable
These shields will fit over glasses. a strip of foam about an inch thick inside the front of the head band will make it more comfortable. the band is round rather than a more oval head shape, so without the foam, there are three (uncomfortable) points of contact with your head: the center of your forehead, and the two points where the adjustable strap attaches. If, like me, your chest hurts after breathing through a cotton mask, this is a viable alternative.<br /><br />I bought a pack of four (seems that option is no longer available.)  The first one out of the box was scratched, dirty, and clearly had been used and returned.  The other three were fine.
