A composition comprises a blend of 50 to 90 wt. % of a polycarbonate copolymer, 10 to 50 wt. % of a polyester wherein the weight percent of the polycarbonate copolymer and the polyester are each based on the total weight of the polycarbonate copolymer and the polyester. A molded sample of the composition having a thickness of 2.5 mm has a luminous transmittance of greater than 80% and a haze of less than 20% when measured in accordance with ASTM D 1003.
