1. A soft contact lens for correcting an ocular refractive error of an eye, comprising:
a soft continuous lens body configured to cover a corneal surface of the eye having an anterior and posterior surface; and
wherein said contact lens has a central thickness of between about 80 microns to about 350 microns; and
wherein the soft contact lens is axisymmetric;
wherein said soft continuous lens body having at least a central aspheric portion and a peripheral aspheric portion;
wherein said central aspheric portion has a base curve of less than 9 mm in its center and a base curve of less than 8 mm in its edge; and
wherein said peripheral aspheric portion has a base curve in its proximal end that is larger than 8 mm and a base curve in its distal end that is larger than 8.5 mm;
wherein at least a portion of the posterior surface of the soft lens body is configured to be suspended above a corneal surface of the eye when placed thereon forming a free volume between the posterior surface of the soft lens body and the corneal surface; and wherein at least a portion of the free volume is configured to be filled with tear fluid to form a tear lens over the corneal surface thereby correcting an ocular refractive error of the eye.
