An ophthalmic lens is disclosed that comprises a first area comprising a plurality of elements selected from the group consisting of: bumps on a surface of the lens; depressions on the surface of the lens; translucent inclusions in a lens material; and transparent inclusions in the lens material, the transparent inclusions having a refractive index different from that of the lens material; and a second area surrounded by the first area, the second area being free of the elements, wherein a density, dimension, and material of the elements are selected 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. Further, a pair of eyeglasses is disclosed that comprises a first ophthalmic lens and a second ophthalmic lens, each of the first and second ophthalmic lenses comprising a pattern of elements selected from the group consisting of: bumps on a surface of a corresponding lens from said first and second lenses; depressions on the surface of the corresponding lens; translucent inclusions in a corresponding lens material; and transparent inclusions in the corresponding lens material, the transparent inclusions having a refractive index different from that of the corresponding lens material; and wherein each of the patterns of the first and second ophthalmic lenses has an area of higher element density in a peripheral region of the corresponding lens as compared to an element density in a central region of the corresponding lens.本発明のいくつかの実施形態では、眼の長さに関する障害の症状を防ぐ、改善する、または、治療するための眼の長さに関する障害の患者への治療的介入に適用できる方法をめざした。本発明の実施形態は、眼の長さに関する障害患者の早期発見のための方法と、眼の長さに関する障害患者のさらなる視力低下を抑制し、眼の長さに関する障害を極力治療し、かつ、眼の長さに関する障害を防ぐための治療方法とを含む。本発明の追加の実施形態では、眼の長さに関する障害患者への治療的介入に用いられる特別な装置をめざした。【選択図】図9C
