Have you tried using contact lenses to make one eye long focus and one eye short focus ("monovision" in intraopticlens terms)? Then you'd only need at most one middle-distance pair of glasses on hand.
Wouldn't you get a headache or have depth perception issues? Whenever I lose a contact in the middle of the day and don't have a spare it's very uncomfortable to keep the other in.
I am not GP, but I don't have a problem with a single contact. What I find really neat is after hours of just one, the vision in my other eye is improved for a while; I can actually see decently from the non-contact eye when I remove the contact.

#73Looks super cool! > It still needs to obtain the necessary medical certifications in order to sell its glasses and get all the production pieces in place Oh, ok. I hope they have enough funding to last till the FDA clears them, in 2030 :/ The same organization which allows any snake oil to be marketed as long as they say it’s a “supplement” will hold a pair of glasses up for years, as though there could be a hidden d…
FDA certification would only be needed to ensure US insurance companies foot some of the bill, surely? It would mean a larger market, but the USA isn't the only market for prescription lenses.

Plenty of us are simultaneously far and near sighted. I can't drive without glasses, but until I got progressive lenses I couldn't use my phone with my glasses on.
If you cannot drive without glasses, the sensible thing is to keep a backup pair in the car. After all, glasses can fall off and get lost under the seat, get stepped on, etc.
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.

#75I pray for the next major development in glasses tech to be some thing that blocks ultra-bright oncoming LEDs while driving.

These glasses address farsightedness, which doesn't apply while driving. Worst case you just take them off.

According to the article the technology can be incorporated into normal prescription lenses, and when the battery is empty, it would behave as that lens without any adaption for when focusing near stuff.

It's not a crisis if you cannot read your dash. How often do you look at the oil pressure gauge, for example? As for speed, just move with the traffic.
I had a car with a broken dash. The only thing I missed for the month until I fixed it was the fuel gauge. I probably didn't estimate my speed very accurately but I was close enough to not get a ticket.
Yes, with my old cars I've had broken dashes, too. I discovered I maintained speed by the engine pitch - because when I drove a silent car, I couldn't seem to maintain a consistent speed!
As for the gas gauge, the trick is to reset the local odometer at every fillup, and you'll have an indication of the remaining fuel. Some older cars don't even have a fuel gauge, they just have a lamp that glows when it gets low.

Keep them within easy reach, like the driver door pocket.

"Monovision" in the in-eye lenses is a very common choice for elderly patients having cataract surgery. There may be a period of adjustment, which you wouldn't have had.

Changing glasses while driving on a high speed lane is dangerous regardless of where you put your spare glasses
