Hello, I have astigmatism on my left eye. My prescription reads -5.50 on left, -6.00 on right. The clinic where ordered my last contacts made a mistake and ordered them without the astigmatism for my left eye. They told me this should not matter or affect my vision, since I have such little astigmatism, but I ve worn them for a few hours and I am noticing difference in my sight. It is distorted and wearing out my vision, especially reading/looking at a computer. Should I order new contacts, or is this normal?
