We've had spiral galaxies and Fillomino (Symmetry), which have tested your grasp of rotational symmetry, leaving reflectional symmetry to idly watch on the sidelines. But today it comes to the forefront in this Sunglasses puzzle, so perhaps it's no surprise that this is the "Coolest" GAPP since Jotunloop.

Rules: 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. The endpoints of each bridge must be shaded, and all other cells on the bridge must be unshaded. Pairs of sunglasses may not share lenses, and lenses may not touch one another orthogonally. A clue outside the grid represents the total number of the shaded cells in the corresponding row or column.

Fairly long rules today! But they should be fairly intuitive. Just think sunglasses which can't touch each other orthogonally.

Note: the presentation of bridges has been altered slightly for penpa input. There is no significant difference made.
