I have been using a competitor brand solution for years and every once in a while, it just makes my eyes dry, red and sometimes my contacts will just float around in my eyes!
I was lucky to receive a sample of BioTrue and have been pleasantly surprised how great my eyes feel since switching.
I have had 1 time where my contact just didn't want to cooperate since sampling BioTrue, but nothing compared to the competitor brand!
I definitely recommend using this brand! Especially if you have been unhappy with your current solution!
