Is there a specific word for glasses that come apart at the bridge?
I have never seen this before, spectacles which come apart in the middle and can be clicked back together again.
Is there a word for this?
One manufacturer (Clic) calls them front-connecting:
Clic goggles is the pioneer in front connecting eyewear.
Apparently they are intended to go over existing glasses, or around helmets and the like, or perhaps where mask loops or hearing aids might interfere with positioning the arms over the ears.
