@shana,
I agree with you that my migraines increased suddenly during the lockdown and mask mandate. I didn't think to point the finger at masks themselves, though I don't have your same eye trouble. I chalked it up to the heightened fear, anxiety, and uncertainty. Also, now I drink far less water than I'm used to because of the risks in removing the mask to drink in public. I look forward to the day when it's safe for us all to remove the masks! I'm sure you've done a lot of research, the head grabber for earpieces squeezes my head too much. But friend of mine has had good results from using one of those bird cage inserts to move the mask away from the mouth a bit. You might give that a go and see if it helps? Good Luck
