@NEWTIE MY BELOVED i think it's because the frame's ends are curved (so that the ears can support the glasses better). I wear glasses too, it won't fall off when i look down. Well.. but when i try to dance or do activities that make me sweat, the sweat on my nose will make the glasses come off more easily. So yeah, it is magic how his glasses stayed in place the whole time he did all that lmao
