Method and apparatus for limiting growth of eye length
Certain embodiments of the present invention are directed to therapeutic intervention in patients with eye-length-related disorders to prevent, ameliorate, or reverse the effects of the eye-length-related disorders. Embodiments of the present invention include methods for early recognition of patients with eye-length-related disorders, therapeutic methods for inhibiting further degradation of vision in patients with eye-length-related disorders, reversing, when possible, eye-length-related disorders, and preventing eye-length-related disorders. Additional embodiments of the present invention are directed to particular devices used in therapeutic intervention in patients with eye-length-related disorders.
1 . An ophthalmic lens, comprising:
a first area comprising a plurality of elements selected from the group consisting of:
(i) bumps on a surface of the lens;
(ii) depressions on the surface of the lens;
(iii) translucent inclusions in a lens material; and
(iv) transparent inclusions in the lens material, the transparent inclusions having a refractive index different from that of the lens material,
wherein the elements are dot-shaped and the ophthalmic lens is configured to introduce higher-order aberrations into images formed in light that has passed through the ophthalmic lens.
2 . The ophthalmic lens of claim 1 , wherein the ophthalmic lens is configured to introduce the higher order aberrations causing blurring in a peripheral visual field viewed through the ophthalmic lens.
3 . The ophthalmic lens of claim 2 , wherein the ophthalmic lens is configured to provide a central visual field in focus.
4 . The ophthalmic lens of claim 1 , wherein the dot-shaped elements are configured to scatter incident light.
5 . The ophthalmic lens of claim 1 , wherein the dot-shaped elements have a dot density in a range between 0 dots per mm 2 and 8 dots per mm 2 in the first area.
6 . The ophthalmic lens of claim 1 , wherein the first area corresponds to a peripheral visual field observed through the ophthalmic lens.
7 . The ophthalmic lens of claim 1 , further comprising a second area free of the elements.
8 . The ophthalmic lens of claim 7 , wherein the ophthalmic lens is configured to reduce a visual acuity from 20/20 when a line of sight passes through the second area to about 20/25 when the line of sight passes through the first area.
9 . The ophthalmic lens of claim 7 , wherein the first area surrounds the second area.
10 . The ophthalmic lens of claim 1 , further comprising a spectral optical filter.
11 . Eyeglasses comprising the ophthalmic lens of claim 1 .
12 . The eyeglasses of claim 11 , wherein the ophthalmic lens is a first ophthalmic lens and the eyeglasses further comprise a second ophthalmic lens different from the first ophthalmic lens.
13 . The eyeglasses of claim 11 , wherein the ophthalmic lens is a first ophthalmic lens and the eyeglasses further comprise a second ophthalmic lens, the second ophthalmic lens comprises a first area of the second lens comprising a plurality of elements selected from the group consisting of:
(i) bumps on a surface of the lens;
(ii) depressions on the surface of the lens;
(iii) translucent inclusions in a lens material; and
(iv) transparent inclusions in the lens material, the transparent inclusions having a refractive index different from that of the lens material,
wherein the elements of the second ophthalmic lens are dot-shaped.
14 . The eyeglasses of claim 11 , wherein the ophthalmic lens is a first ophthalmic lens and the eyeglasses further comprise a second ophthalmic lens configured to introduce higher-order aberrations into images formed in light that has passed through the second ophthalmic lens.
15 . An article, comprising:
an ophthalmic lens; and
a film applied to a surface of the ophthalmic lens, the film comprising particles that scatter incident light, an amount of scatter varying across the ophthalmic lens so that the article comprises a clear area surrounded by a light-scattering area.
