Polarizing sunglasses work by blocking light waves that vibrate in certain directions. When you first put them on, they are aligned to block the horizontally polarized light reflected off the water, reducing glare and allowing you to see beneath the surface. Rotating the glasses 90 degrees changes their orientation, allowing the previously blocked glare to pass through, hence the glare reappears.
