I nearly have to bring a wrench along with me after I have bought my new rimless eyeglasses last mouth, the nuts can get loosen so easily, but I really love rimless frames, Do all rimless eyeglasses can get nuts loosen easily?

Yeah, I have the experience of wearing rimless eyeglasses, at the first one or two months, it works well, but the screw can easily get rotated after a longer period, thus may cuz the hole to be larger, and the nuts can get lost at last, because of high frequency of return back, the price of rimless eyeglasses is usually very high.
