If I remember well the backslash about Google Glass was the camera. People didn't want Glasses inside their shops or generally around them. A camera inside a phone that one has to explicitly point and shoot was and is OK. A kind of hidden camera was not. Contact lenses solve a number of problems especially against headsets. They create others with the interference with vision correction devices but at least one could wear prescription glasses or sunglasses. BTW, I wore contact lenses for about 20 years, then suddenly couldn't wear them anymore and went back to glasses.
