Hi
Just curious your comments on above drops.
Systance Blance has preservative but very little, still bad for eyes? or better NOT to use for more than 1 year or??
Many doctors recommend both but seems more doctors (including my last doctor) recommend Retaine (I guess mainly for its free-preservative) or ?? My eyes seem to like Systance Blance better.
Thanks!
