I had an astigmatism when I was around 8y/o and wore glasses for around 6 or 7 years. I finally kept telling my parents that I could see fine (or good enough) and so I went to another eye exam when I was around 15 or so and the doctor said my astigmatism was gone.
I don't have perfect vision (I can tell), but I have good vision. I can read things up close just fine, a foot away just fine, etc... I can see all the road signs fine. Distances up to around 600+ yds away I'm a little blurry but not blind. When hunting I typically spot deer with ease, when they come around. Even if they are 600+ yds away.
...and on that day when my strength is failing, the end draws near and my times has come, still my soul will sing Your praise unending, ten thousand years and then forevermore!
