Cut 2 or 3 pieces of foamcore to the shape shown above, making sure they're identical, and glue the poster board to the top--that forms the curved shape. That will create a frame, which will then need to be reinforced with more sheets of the foamcore on the sides and bottom (like building a house with a concave roof).
EDIT: I guess the other way to do it would be to get some curved tubing with reflective material and mimic the real eyelighter configuration, but I'm not sure I'm handy enough to pull that off.
