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.
