I bought a pair of relatively expensive flexible frame glasses about a year and half ago. I'm really rough on glasses which is why I splurged on the expensive but forgiving frames. Sadly, I seem to have picked the wrong retailer and ended up with frames that looked nice but were very poor quality!
The first set of frames snapped right in the middle of the bridge about three months after I got them--still under warranty though! The second pair snapped in the same place a couple of weeks ago, and I've been running around with broken glasses ever since. I hate spending money on something like this, especially since the prescription is still fine and the lenses are in pretty good condition!
I've come up with a simple way to make these work until I've got a new pair, and I thought I'd share it with you all.
All you'll need materials-wise is your old pair of glasses (as long as the lenses are still good) and a pair cheap reading glasses from the dollar store. Get the "Rimless" kind of reading glasses, where the bridge and arms are connected by screws drilled right through the lens.
