A shutter slat assembly for a storm shutter, each slat assembly including an elongated horizontally extending hollow shutter slat having longitudinally extending formed outer edges configured to slidably, interlockingly connect with the next adjacent slat for limited pivotal movement between adjacent connected slats sufficient for rolled-up storage of the storm shutter. Each slat has a central port formed therethrough for viewing and light transmission through the port. An elongated transparent panel is also provided having a cross section slidably fitted into the slat and enlarged edge portions configured and spaced for dependent slidable engagement between and within inwardly facing grooves formed inwardly adjacent to the outer edges. The transparent panel covers the port while allowing a person to obtain a view and permit light transmission therethrough. Sliding opaque covers positioned within the slat and over the transparent panel allow for selective closure of light transmission.
