That's maybe Fair given the potential rate of change.

You can go decades without a change, or a significant change (more than half a diopter).

Significant change isn't just the RX, it is other things that can go wrong in the eye as well. IF caught early it can be corrected, otherwise you may not notice until you are half blind.

That's true of everything, though. Your grocery store doesn't say, "sorry, you haven't been to the dentist in 6 months, we can't sell you food", even though there are many dental issues that can be life-threatening if not treated and eating food makes it worse. It's not their business to care.

Yeah, and others may go months, or years too.
