Made for smaller folks. [SEP] Too small for my husband and I. Sheila rested on the tip of our noses, and when you talked your nose came out of the top, exposing it.  Either made for very petite people or children. Not for the average or tall American adult. I’m 5’ 10” tall and my husband is 6’ 4” tall. So I returned them.  Wish they would have worked since we both have had our COVID vaccinations. Had hoped they would not fog up our glasses, and allow others to see you smile.
