How to understand it

This needs a prescribed wear, care and follow-up plan. Daytime vision and underlying eye growth are different outcomes.

An example

Seeing clearly after removing the lenses does not demonstrate that the eyeball has become shorter.

A common mix-up

It is not a reason to sleep in ordinary contact lenses or a permanent cure for all myopia.
