This is a great page on natural vision improvement (excluding the part about the Bates Method, because the Bates Method is not about eye exercises):
It’s taken me a LONNNNNG while (due to various factors/stressors, including “forgetting” about good eye habits), though I tried on my -5.00 glasses today and I’m finally able to see clearly into the distance with them.
My next goal is to get down to -4.00 glasses (after which, yes, I’m going to go for “perfect vision”). In 2009 I did keep to a rather severe schedule where I worked on the computer for a very limited amount of time daily. I didn’t wear glasses for the rest of the day with that schedule. My eyesight did improve within a relatively short time frame (then I experienced a couple of stressful events and bam, there went my vision improvement).
I’ll do my best to stay committed to getting it down to -4.00 this time (that was my first “major goal” from original prescription of -7.25, followed by the next “major goal” to get it down to perfect vision).
