Abstract

An adaptive spectacle lens includes a spectacle frame and a pair of progressive additional lenses mounted to the spectacle frame. Each progressive additional lens includes a distant vision region positioned at an upper portion. The distant vision region has a diopter of zero and functions with a pair of main lenses.

First claim

What is claimed is:

1 . An adaptive spectacle lens comprising:
a secondary spectacle frame; and a pair of additional lenses mounted to the secondary spectacle frame, each additional lens comprising a distant vision region positioned at an upper portion of the additional lens, and the distant vision region having a diopter of zero.

2 . The adaptive spectacle lens of claim 1 , wherein the pair of additional lenses are progressive additional lenses made of cyclic block copolymer (CBC) by injection molding.

3 . The adaptive spectacle lens of claim 1 , wherein the pair of additional lenses has a curvature of +2.50 D to +10.00 D.

4 . The adaptive spectacle lens of claim 1 , wherein each additional lens further comprises a near vision region positioned at a lower portion of the additional lens, and an intermediate vision region between the distant vision region and the near vision region.

5 . The adaptive spectacle lens of claim 4 , wherein the near vision region has a diopter of +0.75 D to +2.50 D.

6 . The adaptive spectacle lens of claim 4 , wherein each of the distant vision region and the near vision region has a width of about 6 mm to about 20 mm.

7 . The adaptive spectacle lens of claim 4 , wherein the intermediate vision region has a length of about 15 mm to about 25 mm, and a width of about 2 mm to about 7 mm.

8 . A spectacle lens assembly comprising:
a main spectacle lens comprising:
a main spectacle frame; and
a pair of main lenses mounted to the main spectacle frame; and
an adaptive spectacle lens comprising:
a secondary spectacle frame connected to the main spectacle frame; and
a pair of additional lenses mounted to the secondary spectacle frame, the pair of additional lenses covering the pair of main lenses, each additional lens comprising a distant vision region positioned at an upper portion of the additional lens, and the distant vision region having a diopter of zero.

9 . The spectacle lens assembly of claim 8 , wherein the secondary spectacle frame is removably connected to the main spectacle frame to allow users to selectively combine effects of the main lens and the additional lens.

10 . The spectacle lens assembly of claim 8 , wherein the pair of additional lenses are progressive additional lenses made of cyclic block copolymer (CBC) by injection molding.

11 . The spectacle lens assembly of claim 8 , wherein the pair of additional lenses has a curvature of +2.50 D to +10.00 D.

12 . The spectacle lens assembly of claim 8 , wherein each additional lens further comprises a near vision region positioned at a lower portion of the additional lens, and an intermediate vision region between the distant vision region and the near vision region.

13 . The spectacle lens assembly of claim 12 , wherein the near vision region has a diopter of +0.75 D to +2.50 D.

14 . The spectacle lens assembly of claim 12 wherein each of the distant vision region and the near vision region has a width of about 6 mm to about 20 mm.

15 . The spectacle lens assembly of claim 12 , wherein the intermediate vision region has a length of about 15 mm to about 25 mm, and a width of about 2 mm to about 7 mm.
