How can i correct if i am nearsighted in one eye and farsighted in the other?

With eyeglasses: Most eyes are within a small distance of each other in eyeglass power needs. If the numbers are small, and near the neutral point, sometimes one falls on the nearsigted side and the other on the opposite side. Correction of each usually does the trick. Rarely the difference is so great that correction is uncomfortable but this is pretty rare.
