Abstract

A corrective lens for correcting aberrations of an eye of a patient includes a central region formed in the center of the corrective lens preventing light transmission. The corrective lens further includes a slotted transmissive region formed in the central region, the slotted transmissive region allowing light transmission therethrough.

First claim

What is claimed is:

1 . A corrective lens for correcting aberrations of an eye of a patient, the corrective lens comprising:
a central region formed in the center of the corrective lens preventing light transmission; and a slotted transmissive region formed in the central region, the slotted transmissive region allowing light transmission therethrough.

2 . The corrective lens of claim 1 , wherein the slotted transmissive region is formed in the center of the central region.

3 . The corrective lens of claim 1 , wherein the slotted transmissive region is formed spaced from the center of the central region.

4 . The corrective lens of claim 1 , wherein the lens improves depth of focus to improve retinal image quality of objects that are at far, intermediate, and near distances from the eye.

5 . The corrective lens of claim 1 , wherein the lens is one of a soft contact lens, hard contact lens, spectacles, and an intraocular lens.

6 . The corrective lens of claim 1 , wherein the corrective lens has an orientation when worn on the eye, and the slotted transmissive region is elongated in a horizontal direction relative to the orientation of the corrective lens when worn.

7 . The corrective lens of claim 1 , wherein the corrective lens has an orientation when worn on the eye, and the slotted transmissive region is elongated in a vertical direction relative to the orientation of the corrective lens when worn.

8 . The corrective lens of claim 1 , wherein the corrective lens has an orientation when worn on the eye, and the slotted transmissive region is elongated in a diagonal direction relative to the orientation of the corrective lens when worn.

9 . The corrective lens of claim 1 , wherein the slotted transmissive region has non-parallel long sides.

10 . The corrective lens of claim 9 , wherein the slotted transmissive region has curvilinear long sides.

11 . The corrective lens of claim 1 , wherein the central region is printed onto a surface of the corrective lens.

12 . The corrective lens of claim 1 , wherein the slotted transmissive region includes an aperture disposed through the corrective lens.

13 . The corrective lens of claim 12 , wherein the central region includes an opaque pigment in a material of the corrective lens, the aperture being formed subsequent to the opaque pigment being added.

14 . The corrective lens of claim 13 , wherein the aperture is formed through the corrective lens with a laser.

15 . Corrective lenses for correcting aberrations of eyes of a patient, the corrective lenses comprising:
a first corrective lens and a second corrective lens; a first central region formed in the center of the first corrective lens, the first central region preventing light transmission; a second central region formed in the center the second corrective lens, the second central region preventing light transmission; a first slotted transmissive region formed in the first central region, the first slotted transmissive region allowing light transmission therethrough; and a second slotted transmissive region formed in the second central region, the second slotted transmissive region allowing light transmission therethrough.

16 . The corrective lenses of claim 15 , wherein the first corrective lens has a first orientation when worn on a first eye, the second corrective lens has a second orientation when worn on a second eye, the first slotted transmissive region is elongated in a first direction relative to the orientation of the first corrective lens when worn, and the second slotted transmissive region is elongated in a second direction relative to the orientation of the second corrective lens when worn, wherein the first direction is different from the second direction.

17 . The corrective lenses of claim 15 , wherein the first slotted transmissive region formed in the first central region has a first shape, the second slotted transmissive region formed in the second central region has a second shape, and the first shape is different from the second shape.

18 . The corrective lenses of claim 15 , wherein at least one of the first slotted transmissive region and the second slotted transmissive region is formed in the center of the respective first and second central regions.

19 . The corrective lenses of claim 18 , wherein both the first slotted transmissive region and the second slotted transmissive region are formed in the center of the respective first and second central regions.

20 . A method of correcting aberrations of an eye, the method comprising positioning a corrective lens to an eye, the corrective lens having a central region formed in the center of the corrective lens, the central region preventing light transmission, and a slotted transmissive region formed in the central region allowing light transmission therethrough.
