Or they could just ban using these glasses while driving. There’s plenty of people who don’t actually need to drive who would buy this.
replyI think enforcement would be poor and therefore abuse would be high, but it could be granted that they're not safe for driving and therefore if you own a pair, you must switch to different (your old regular dual focus lenses) when driving.
replyEqually hard to enforce as people driving without their normal prescription glasses.
replyIn both cases enforcement is reactive and happens after an accident has already happened.
