I've been reading your thread. I can't say I understand the visions at all, but if I ever told you what I've seen, you probably wouldn't understand it either. Our cultures are so different, just that makes it get lost in translations. But, I do get God started calling you on October 10, 2008.
Might I make a suggestion that spans all cultures? Instead of seeking signs, (and it is a wonderful feeling when given a sign, so I do get why it would be easy to keep seeking signs themselves), seek the Lord instead. His signs are amazing, but that's just the tip of the iceberg. There is so much more than that.
As for myopia? We're more apt to call that nearsightedness in English. It's not a disease. It's not that big a deal, thanks to the Lord for someone inventing eyeglasses. But I know there are moments when I can see clearly, and most moments I need my glasses. Assume you get what most people get -- old-age eyes the older you get. My husband was born with more-than-perfect eyesight. He had 20/10 eyesight. (What most people can see at 10 feet, he could see at 20 feet.) Now he is 71 years old, and bemoaning needing glasses. But, truthfully, he felt like he needed glasses 20 years ago and his eyesight got "so bad" he could only see like most people. Now his eyesight is as bad as mine was at birth. 20/50. (What most people can see at 50 feet, we could see at 20 feet.) For me, I'd still would like 20/50, because mine got worse.
All in all, it really doesn't matter, because we can see 20/20 with glasses.
All that just to say, myopia isn't one of those things we need a miracle for. We don't really need miracles. What we do need is the Lord.
