Swimming goggles protect your eyes from exposure to water. Goggles are especially useful in chlorinated pools, where the chlorine can make your eyes burn, and in sandy or murky water, where visibility is poor and sand and other debris can get in your eyes. Goggles are only useful, however, if they fit properly.
The rubber or silicone band connected to the swimming goggles is supposed to be fitted around the upper part of your skull, where the slight bulge in your skull is. Run your hand up the back of your neck to the top of your skull to feel the bulge; that is where the band should fit. Some goggles have two bands; these should be positioned at the top of the skull, about an inch and a half apart.
Goggles should be centered on your face so that each cup covers each eye entirely. Most goggles have adjustable plastic nose bridges. Push the nose bridge out or together between the two goggles (see picture in resources) to adjust. Note that some goggles do not have adjustable nose bridges.
Tightness of swim goggles
Make sure that the goggles completely cover all the parts of your head for a proper fit. The goggles should feel like a headband that touches every part of your head. If too loose, pull the rubber band tighter through the goggle loop; if too tight, loosen. While swimming goggles are supposed to fit snugly around your head, if they are too tight you may have a headache after a short while.
If the goggles are properly attached to your face, no water will seep past the goggles and into your eyes. If the band and nose piece are correctly adjusted but water still seeps in, adjust the placement of the eye cups in your eye sockets until you get a proper seal.
Putting on Goggles
The proper way to put on goggles is to fit the eye cups over your eyes and then pull the band back to its position. Goggles can go under or over a swim cap.
