:{{Re|Heddy}} I know Jake has attempted to describe it as a principle, but he also says "Active focus is a key activity..." in this page [https://endmyopia.org/active-focus-links/ Focus: The Link List (+ Video Explainer)]. I think Jake wants to call it a principle because he wants to differentiate it from eye exercises. However, it still makes no sense to call it a principle, because most people consider active focus as something they do, as in "do active focus". One cannot do a principle.[[User:SilentNote|SilentNote]] ([[User talk:SilentNote|talk]]) 14:09, 11 June 2020 (UTC)

==Excessive sharpness==

"excessive sharpness is the stimulus that increases the axial length of the eye"... that's a new one. Do we know what that means, and is there evidence that it causes elongation ? [[User:Divenal|Divenal]] ([[User talk:Divenal|talk]]) 16:49, 10 June 2020 (UTC)

Is this stuff relevant ? Accommodation (by the usual definition) is about increasing focusing power to focus on nearer objects. AF is about trying resolve myopic blur, which means (somehow) reducing focusing power. (There are some heretical discussions on the forum about possible links, but ...)

::{{re|SilentNote}} is it actually established that AF is related to accommodation ? It's certainly a possible mechanism, of course. (And I am rather liking it.) But is it doctrine ? [[User:Divenal|Divenal]] ([[User talk:Divenal|talk]])
