Similarly, if a FAA-licensed pilot requires glasses to fly, it becomes a legal requirement that they carry a readily-accessible second pair while exercising the privileges of their license. This even applies if they use contacts (and, no, extra contacts don’t count :).
replyIt is also a requirement for international flight operations under ICAO regulations. I’m pretty sure this regulation (or something close to it) is enforced by just about every flight-licensing authority worldwide.
It’s plain good sense and I’m glad it’s in there. A plane cannot pull over to the side of the highway while the pilot fumbles around trying to dig his glasses out from under the seat :)
(As a side note, this rule isn’t just for dropped spectacles: there have been cases where they literally get sucked out of the airplane if a cockpit window fails or where a bird strike causing facial injuries also damages the pilots glasses).
Still doesn't address the fact that if the glasses fail mid drive it poses a serious security risk if you can't pull over to switch glasses. Doing so in a highway in a moving car is inadvisable regardless of the technology behind the glasses.
replyKeep them within easy reach, like the driver door pocket.
replyChanging glasses while driving on a high speed lane is dangerous regardless of where you put your spare glasses
replyConsidering what people do whole driving, I doubt this will add any measurable risk.
replyOn the contrary, if you are a perfect driver and only reach for you glasses, that adds a small risk. But this is a complex system, driving and multitasking, so added complexity surely compounds, maybe even exponentially. If you are texting, then talking to your kids, then your brother next to you starts blasting loud music on the radio, adding another task like changing glasses increases the risk of an accident a lot, because less and less you are concentrated on the traffict.

replyThat's a smart idea, similar to how I keep a little cash in the car just in case. For example, I could get something in my eyes and have to remove my contacts, and an old pair of glasses would let me get home.
replyThis is why I keep a pair of prescription sunglasses in my car. Added bonus is cutting the astigmatism glare while driving at night.
