Light shielding devices are created from opaque, light absorbing strips (39), created by coating the strips (38,39) with a, preferably, black light-absorbing coating, and arranging the strips to extend to the surface or surfaces of a transparent material in which the strips are encased, enclosed or embedded. Strips (38, 39) installed in a parallel arrangement provide a low glare collimating effect to transmitted light for either illumination or observation. Selected sides of a plurality of strips (38) may have a reflective finish such that the arrangement of the strips may either enhance the collimating effect or alternatively create a dispersing effect. Disclosed embodiments include: an overhead incandescent light shield, a bollard light shield, an overhead fluorescent light shield, a window shield, a vehicle dashboard, a pool light cover, and sunglasses.

A method of constructing a light shielding article, said method comprising the steps of providing at least one thin element defining at least one light absorbing surface and at least one light reflecting mirror surface, said light absorbing surface being spaced from and facing said light reflecting mirror surface, providing a transparent material between said surfaces, said transparent material being in contact with the respective said surfaces and defining between said surfaces, a passageway for the passage of light.
A method as claimed in claim 1 wherein said at least one element comprises at least one pair of spaced apart elements, one said element of said pair having said light absorbing surface and the other said element of said pair having said light reflective mirror surface.
A light shielding article having at least one thin element defining at least one light absorbing surface and at least one light reflecting mirror surface, said light absorbing surface being spaced from and facing said light reflecting mirror surface, and a transparent material between said surfaces, said transparent material being in contact with the respective said surfaces and defining between said surfaces, a passageway for the passage of light.
