I've had several pair of Tifosi sunglasses over the years. My go-to pair at the moment are from their Light Night line (I got them at TE). They change from clear to a smoke tint depending on conditions. I also have a pair of their Fototec lenses, but I found they didn't get light enough in low-light conditions, so I switched primarily to the Light Nights. If I'm really going to be in full sun the entire ride, then I might opt for the Fototecs, but I otherwise prefer the Light Night so that I can see in shade. I just don't really like to fiddle with changing lens out based on the conditions. They're pretty light and comfortable. I'll admit, however, that I haven't really tried other brands.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
