Thanks for your reply.
I understand the game idea, but I can’t rely solely on such things. What works for him is when he stacks habits on top of one another. Like, to practice AF for 3 distances * 5 minutes after each meal.
This is why I’m asking about the min, optimal, and max time for AF.
Could you pls also clarify:
1) should the AF be practiced with or without glasses? Or, both?
2) at what distance does practicing AF drive the most impact? Like, if we presume “distance vision improves distance vision” then we should get the most results practicing it on distance, like, 5 minutes from 5 meters, 5 minutes from 10 meters, and AF from 60 cm doesn’t move a needle considerably. Maybe he should only practice it outdoors for gaining the most results per time spent?
3) what about AF on distance objects that can’t be seen totally cleared up? Like, when you’re outdoors and see a street name from 200 meters, you can try to clear it up, but it won’t become 100% clear cause it’s too far. Should he practice AF on such things or only on things he can clear up to 100% clarity?
4) What works better: let’s say, he practiced AF on a 20/20 line of an eye chart, cleared up the first blur on ~90 cm. What is better now
– to sit a bit farther from the chart and clear the new blur on the same 20/20 line and repeat this a few times
– to pick a different object from a considerably different distance, like to practice AF on 20/50 line from a couple of meters, and then to move back and challenge a different row from a different distance?
5) When he practices AF on a text, what is better: to focus on 1-2 letters or to try to widen his focus area into more letters, like, 5-10 letters?
(When I took speed reading classes at school age, we were taught to widen our area of clear focus, from a word to a few words, then to a line in a book, then to a couple of lines. Pilots do similar things when they learn to monitor many instruments’ readings simultaneously. But, I’m not sure if it makes sense, if it provides value, if it doesn’t worsen myopia)
6) should the AF be practiced only when looking directly at an object or it also makes sense to practice it when you move your eyes for it without moving your head? For instance, there are 5 cars on a parking lot. One could practice AF on 5 license plates, standing behind the 3rd car, but looking at a license plate of the 1st and 5th car without moving your head. The angle isn’t too wide, but just enough to use the muscles that he doesn’t use because of glasses.
What I’m thinking about is that in real life a person that has 20/20 vision sometimes looks at objects that aren’t in front of them just via moving eyes. But a person in glasses almost doesn’t use such muscles that move eyes to sides and top/down.
