Laminar fresnel reduced ophthalmic lens construction

A multi-element ophthalmic lens comprising,

• a plurality of two element lens pairs bonded together, each two element pair comprising,
• a. a first optical element having a smooth, front, convex said defining a first preselected curved shape, a rear side defining a second preselected curved shape which is toric and reduced in thickness by a first plurality of Fresnel echelons and made of a material having a first index of refraction,
• b. a second optical element having a smooth, rear, concave side defining a third preselected curved shape identical to said first preselected curved shape, a front side defining a fourth shape which is toric and reduced in thickness by a second plurality of Fresnel echelons mating with said first plurality of Fresnel echelons and made of a material having a second index of refraction, and
• c. a bonding means for bonding said first and second elements together and bonding pair elements at rotational angles of said first and second optical elements such that the alignment of said toric shapes gives a desired ophthalmic correction.

• a second optical element having a rear, concave, side defining a third preselected curved shape identical to said first preselected curved shape, a front side defining a fourth curved, preselected shape, reduced in thickness by a second plurality of Fresnel echelons mating with said first plurality of Fresnel echelons and made of a material having a second index of refraction,
• a first bonding means for bonding said first and second optical elements together,
• a third optical element having a front, convex, side defining a fifth preselected curved shape, reduced in thickness by a third plurality of Fresnel echelons and made of a material having a third index of refraction,
• a fourth optical element having a rear, concave side defining a seventh preselected curved shape, identical to said fifth preselected curved shape which, in turn, is identical to said first preselected curved shape, a front side defining an eighth curved, preselected shape reduced in thickness by a fourth plurality of Fresnel echelons mating with said third plurality of Fresnel echelons and made of a material having a fourth index of refraction, and
• second bonding means for bonding said third and fourth optical elements together and third bonding means for bonding the combination of first and second optical elements to the combination of third and fourth optical elements.
