These adhesive nose bridge strips help keep my glasses from fogging up.
I have two masks that came with nose bridge strips sewn in. Those two are the only masks I was able to use when shopping or anywhere my sight was actually important, as the loose nose bridge area on my other hand-made masks encouraged my glasses to fog up.
Feeling like my vision is closing in as I breathe-in increasingly warmer and damper air evokes memories of nitrogen narcosis while scuba diving. Never the smartest free ride.
I did not know I was looking for these adhesive aluminum strips until they found me. Today, they are pretty much the best cheapo gadgety thing I've seen this pandemic.
