making mold 30 having an upper half 44 and a lower half of the mold 30 where multiple micro lines 34 are imprinted on the inner wall of the upper half of the mold 30 b depositing liquid resin along the inner wall 32 in the cavity between the lower and upper halves 44 of the lens making mold 30 where the conventional cast molding technique is used with the aid of the upper half 44 to shape the resin layer by squeezing the liquid resin to make the resin spread out evenly over the lower half of the lens making mold 30 c casting an uv ray 38 on the resin layer to cause the resin to solidify under the uv irradiation and to develop into the shape of a contact lens 36 d removing the lens making mold 30 and retrieving the contact lens 36 between the upper and lower halves of the mold 30 where the micro lines 34 have been successfully copied onto corresponding light interference zone 40 on the inward bending side of the contact lens 36 and e forming an optical coating 42 over the contact lens 36 including the light interference zone 40 over which multiple micro lines have been formed case 4 referring to fig6 the fabrication of the holographic contact lens as the fourth embodiment of the invention demonstrates is accomplished by a conventional cast.
