I didn't have glasses (lens) as a teenager, so I wasn't wearing any up to when I got to about -2.0/-1.5. From that time I was generally wearing glasses more often than not, and my eyesight hasn't dramatically changed. For me your theory simply doesn't hold.

It's not "my theory" ;) Myopia is usually caused by a combination of lifestyle and lens use. For example looking at a phone 33.33cm away is equivalent to wearing a -3 lens and looking into the distance.
