In my opinion a total waste of my time and money. this HACK took me for over a total $100 and I still CAN'T SEE with his Rx. you call to inform them and all you get is the front desk and this person ( with no Od ) turns it around on you and says its all your fault. the HACK said that I was all over the place, (how do you fail a eye exam). so if you see me coming get out of the way because I can't see you.
