I bought these sunglasses primarily for rock-hounding trips because they flip up. However, they are also great for running errands around town. It's really convenient to just flip them up when you go indoors for brief periods of time. Lens are good quality with no color changes or distortion. The fit is good but maybe tight on someone with a larger head. Only down side so far is they are a little heavy but they do not slide down my nose.
