I have so many masks and they all make my glasses steam up and also push them out of focus (they are varifocals) so I dreaded going out more because I could not see properly, or hear properly because whilst I do not wear hearing aids I obviously lip read) than catching the virus. When I saw these masks were designed by doctors at Alder Hey I decided to give it one last shot. I was glad I did. I will order another one but they are expensive so it will have to wait till next month, but order again I will. ,
