If you have astigmatism, I would bet that your lens is spinning slightly when you shift your eyes to that angled position when you shoot, causing your axis to change. With astigmatism, your axis has to be dead nutties to see perfect. If the contact is inverted (inside out) or your axis is a few degrees off, you won't get as sharp of picture. Toric lenses are weighted and desinged to stay at the axis that they are which depending onyour RX is between 0 and 180. If that axis is off by a mere few degrees things will be out of focus. The higher the astigmatism the greater the demand that your lensesstay anchored. Try focusing more through the center of the lenses when shooting and see if that makes a difference.
