The perfect solution
People wearing glasses often complain about losing them, forgetting them or leaving them behind at odd places. This guy (who strangely doesn’t seem to be wearing real glasses) has found a way to never forget or lose his glasses ever again.
It’s also quite possible that he doesn’t even require glasses, but he simply likes the way it looks – like an accessory. There’s only one problem with that logic – what happens if he wants to change the frame? Sure, the big ones are in fashion today, but the fashion world is dynamic, and no one is to say what might happen in another couple of years.
