The use of polycarbonate material for the lenses in the Tom and Jerry T & J 4003 Kids (6-10 yrs) (Size-53) Matte Black Red Grey C5 Kids Polycarbonate Sunglasses makes them comfortable to sport. Why? Because, not only are these shades lightweight, they have polarized lenses that reduce strain and glare on the eyes too. These are perfect for kids who want to sport colorful and fashionable sunglasses outdoors, and also have a love for the cartoon 'Tom and Jerry'. This pair of sunnies would look good with plain casual tops and pants or with sportswear.
