when you hang the chain off the back of your head is allows it to be
pulled by anyone walking by but of course you may ask who would pull it most
likely friends or jokers who feel it's funny to do that but beyond the
intention although once it hangs off the back of your neck this to other
problems and one is that it can get snagged on things that pass by or when you
pass by things it could get snagged on it and that's dangerous and to it
doesn't feel good when you let it hang off the back of your neck so be it
eyeglass chain or eyeglass cord there some resistance there what I mean is that
it makes contact with the back of your shoulders and you weren't close of
course and it creates a sense of frictions that whenever you turn your head it
feels like there is resistance and it's uncomfortable. But there is a safer way to stop your glasses from falling.
