Active Focus is far and away the biggest pitfall/misconception for newcomers. Usually the first thing people think is that it’s an eye exercise/some wacky internet sales pitch.

Possible mention of that study mentioning transient AL change with increased accomodation.
Mainly the first three paragraphs.
