Please choose the correct ending to complete the given sentence: Sports and Fitness: [header] How to fit swimming goggles [title] Test the seals of the eye pieces with your face shape. [step] Place each pair of goggles over your eyes without fitting the straps around your head. Use your fingers to press the goggles gently onto your eyes.

Ending1: Be extremely careful while moving over the eyedropper holes that the goggles will be fitted against-the goggles themselves will be too small to fit over the eyes. [title] Observe the materials and clamps on the goggles after driving. Ending2: The goggles should cover over your eyes, leaving you completely exposed! [substeps] Eye pieces that are too loose will fall off easily while under water. They will also be hard to fit over other glasses. Ending3: If they have enough suction to seal to your face for 3 to 4 seconds, they're a good fit. If they pop off, look for a smaller size. Ending4: Test if your goggles fit and adjust the size and tightness of the lids to ensure that they fit correctly. [substeps] Your goggles should fit the total seal of the eye pieces with nothing too big or too small.
