so we are at the beginning of this industrial revolution. the aim here is what is being called mass customisation — where by making lots of personalised products, the cost can be kept down. and although these glasses do start at £160, which is similar to many others on the shelves, that rises with some of the options. but beyond all of this, and the sustainability element, for this to really work, the finished product needs to prove to be the perfect fit. 0k, well your glasses have arrived now, do you want to pop them on for us? they are super light and really comfortable, but the thing that i noticed more than anything was in the shop when i was trying them on, everything looked a bit wonky. i always have this with sunglasses, where one eyebrow shows and the other doesn't, so clearly i have a wonky face. and these glasses seem to fix the issue. the glasses are maybe as wonky as my face...
