I have several pairs of glasses, 5 in fact. They are cheap, $15 ones I buy for Target to help me read and work on the computer. The screw in the bridge got loose and for ages I’d just tolerate it. They would slip down my nose, fall off if I looked down and sit awkwardly. Eventually, I woke up and bought another pair (I have them all over the house in specific locations and in my purse) and donated these. Ahh, bliss. Why did I wait so long?
