Insects have compound eyes. Instead of one lens they see through two spheres with many lenses. But apart from that they also often have extra single lens eye on the front of the head. Each lens of the compound eye catches it's own image. The final image an insect sees is like a mosaic. The more lenses the compound eye bears the higher the resolution of the image. The two large spherical eyes of a fly give an almost complete 360 degree vision.
