My eyes tear up when I walk so I needed glasses to cut the wind.  The "sport" sunglasses didn't look too much better than my regular sunglasses and were 3 times the price!  I got 3 pairs for, including shipping, $20!!!  They work great!  I have a small face, which I think another reviewer had said as well so I knew they would fit!  I use the grey shaded ones in the bright sunlight, the yellow when it's in between or getting dark, and I use the clear ones on cloudy days.  The clear ones look a tad funny; look very geeky but I don't care one bit and you can always use the yellow ones instead.  Keep the wind out beautifully and my eye-makeup stays put (VERY important!).
