1. method that is used to design contact lenses, this method may further comprise the steps:

  • Use corneal profile surveying instrument or video keratoscope to obtain the corneal profile information of human eye;

    Use wavefront sensor to measure the summation of the optical aberration of said human eye;

    Utilize corneal profile information to confirm the back surface of contact lenses;

    Machine-shaping is used to compensate the back surface of the surperficial contact lenses of cornea;

    Deduction is owing to the optical aberration that back surface produced of described contact lenses, to produce the remainder optical aberration from the optical aberration summation;

    AndUtilize the remainder optical aberration to calculate the contact lenses front surface.
