太阳镜 Sunglasses

标准数独基础上，涂黑一些单元格作为太阳镜。每个太阳镜上拥有一座桥，以及两个镜片。两个镜片关于一座已经给出的桥对称，并且对称位置拥有相同的数字。不同的镜片之间不能水平或者垂直接触，并且同一个太阳镜内部也不能连结（除了在桥的部分）。外提示表示了该行列中有多少格是镜片。

Classic rules applied. Additionally, shade some cells to form pairs of sunglasses, each consisting of one of the given bridges and two lenses made of orthogonally connected shaded cells which are symmetric with respect to the perpendicular bisector of the bridge. Pairs of sunglasses may not share lenses, and lenses may not touch one another orthogonally. Cells with bridges cannot be shaded, except at bridge ends. A clue outside the grid represents the total number of the shaded cells in the corresponding row or column.
