Principle vs activity

- @SilentNote: Yes, it's a principle as defined on Jake's blog. An example of an activity would be print pushing. Heddy (talk) 13:33, 11 June 2020 (UTC)
- @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 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.SilentNote (talk) 14:09, 11 June 2020 (UTC)
"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 ? Divenal (talk) 16:49, 10 June 2020 (UTC)
@SilentNote: (I think you introduced this ..?) "As accommodation is an automatic activity, active focusing is not straight forward. While it is easy to move the skeletal muscles of your body, it is not possible to control the ciliary muscles in the same way. However, by careful manipulation of the blur horizon, it is possible to encourage the eyes to push slightly harder to achieve focus."
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 ...)

- @Divenal: 1)Accommodation is the process of bringing a subject into focus. It is not limited to an increase in power alone Glossary of Eye Terms. The reason I wrote these sentences is to differentiate the conscious control of skeletal muscles vs autonomic control of smooth muscles without being too technical. 2)Wait... are we not doing links??SilentNote (talk) 14:10, 11 June 2020 (UTC)
