Hello!. I'm now 48 y.o.. I noticed I had my left lens with
stronger prescription when I was 28 y.o. And I
had vision therapy for convergence.
Since then, and after Lasik surgery.
My left eye has been weaker. Now left eye is -4.00
right eye has not changed, -1.50 from Dec 2010's eye exam.
I wonder if premature birth causes it. (I was born premature).
Thanks.
