Power given by opthamologist was sph-1.00, cyl-1.00 and an axis of 170 in each eye. The person who we bought contacts from(a spectacle shop) gave the power sph-1.00, but cyl-0.75 and axis of 180. They said that the cylindrical power has to be reduced by .25 and thus gave -.75.And the axis is off by 10. Are these the contacts i should use? The brand of contacts is 'Bausch and Lomb'.
