It is not true, but I carry one anyway

Very wise. I carry my old glasses in my fishing vest (looks silly, I
know, but it's a great way to get all the miscellaneous stuff on my
person). The prescription is far from current, but good enough to get
the plane on the ground.

If you'd have trouble landing the plane without corrective lenses,
then a backup is surely in order.
