1. A sun protection device, comprising:
a main body, having an outer surface and an inner surface opposite to each other, and the outer surface being configured to face sunlight, and the main body having a plurality of voids disposed inside the main body, on the inner surface of the main body or a combination thereof, wherein when the sunlight irradiates the outer surface of the main body, a first reflected light and a first refracted light are formed, and the first refracted light enters the main body, and when the first refracted light arrives at a surface of one of the voids facing the outer surface, a second reflected light is formed; and
an S-type polarizer adjacent to the inner surface of the main body.
