Had my eyes checked at Sears Grand Canyon by Monica the prescription she gave me was way to strong , the glasses came back and I could not see she told me to try for at least 10 hours I did and could not see anything went back to her she tried to tell me I was wrong and that what she gave me is what I need she had a attitude said OK will write you one for your old prescription if that's what you want I said I just want to be able to see she continued to write old prescription she handed it to me I took it and left what a waste of time don't waste yours
