Add driving to your list. I consider sunglasses to be an essential safety item when driving.
I guess if the situation was right driving might require sunglasses as a safety item. I keep sunglasses on the visor but even good ones might not be sufficient. A lot of the roads around Florida seem to be aligned perfectly for maximum glare and, outside some earth shattering need to make time, I don't know ... an incoming nuclear warhead, or the fresh doughnut sign coming on at Krispy-Kreme, one has to have priorities, I often just pull over for fifteen minutes. A cup of coffee and a doughnut perhaps.
{How it would shake out if the Krispy-Kreme light came on and a warhead was incoming is still up in the air.}
I'm always surprised that survival kits intended for sea survival so often lack sunglasses. Anyone who has spent time on the water knows just how brutal the sun can be. Or how debilitating sun damage to eyes can be if you are in a small boat and are forced by a needed to scan for rescuers.
