On Saturday afternoon, my uncle, dad, and I, went fishing.  We went to many reefs and tried to catch pupio and barracuda.  Because the sun was already high overhead, the light from the sun reflecting off the surface of the water caused massive glare and hindered our progress.  When we put on sunglasses, the glare was significantly cut down.  This is because the sunglasses we used were vertically polarized.  When the unpolarized light from the sun reflects off the surface of the water, it becomes horizontally polarized.  Our vertical polarized glasses only allow vertically polarized light through which means it doesn't allow the horizontally polarized light (glare) to go through.  The glare was erased and we were able to catch 3 fish.
