Why can't you wear goggles when snorkelling?

Goggles are designed to protect your eyes from the water, yet to be sleek and unobtrusive at the same time, so as not to interfere with your speed and motion. The rubber that surrounds the goggles is meant to keep water away from the eyes. ---- Note that diving to any depth over perhaps 6' with goggles that do not encompass the nose can cause a wide range of injuries. The pressure inside the goggles remains constant, as the external pressure increases. This is compensated by compression, where the goggles are pressed deeper into your eye sockets, hemmorhage, where blood takes up the slack, or a variety of other equally unpleasant events. Divers get around this by having masks that cover the nose as well, so you can expel air into the mask, thuse equalizing the pressure. Cjonb 23:26, 2 Jun 2008 (UTC)
