Inner Bracket for masks

Today is a Christmas eve.Just off the zoom with my in-laws. My father in law wears glasses, he told us he recently discovered an Inner Bracket for masks not only give him a Comfortable Breathing but also prevents foggy glasses due to the breathing. I am posting the picture here. If you wear glasses too, you may want to give it a try:) 

Wishing you a very happy Christmas and a safe and healthy 2021！
