Eliminating the need for glasses or contacts

I am wondering if I can gradually wean myself off of contacts/glasses. I am 27 years old and have been wearing corrective lenses for 5 years, I got my prescription -1.50/-1.75 back then and it has stayed the same ever since with the -1.75 going down to -1.50 one year and back up the next. My up close vision is perfect and if I go without glasses my vision is better by evening.

The other day while experimenting with an eye exercise I stumbled upon all by myself, I found that after roughly 30 seconds of repetitions I could focus on more distant objects (specifically text) and they were much clearer, albeit only for a short time before I would have to blink. I have a limited understanding of how the eye works but from what I understand this exercise forced the eye to refocus back and forth while never looking away from the same object by changing the level of light taken into the eye. (I use non-prescription sunglasses that I flip up, focus, flip dow, focus, repeat, repeat.)

I got my glasses at a time when I was spending most of my waking hours in a small "office/cubicle" at work, roughly 36x36 inches. (private school, weird setup, etc. etc.) and my eyes didn't get a lot of outdoor, long range use at that time.

What I'd like is to find an eye doctor who will prescribe me weaker corrective lenses, say -1.00 or whatever it takes to get me just inside the legal requirements and then later on a weaker ones so I can still drive, etc. and pursue this exercise without using my normal prescription since it seems to ruin all progress as soon as I have to use corrective lenses to drive. Is there any legal implications in a doctor doing this for me?
