Cheap Serengeti Medium Aviator Sunglasses,silver frame Review
I bought these glasses because I wanted something optically correct (meaning that things don't change shape and/or size when one views them through the lenses), something with a full coverage and a good history. These glasses fit the bill. I use them for flying almost 6x a week and they do a great job of cutting down on the brightest spots while increasing the dynamic range of the light emitted (so the contrast is higher while not being painfully bright). They are durable as well. My only negative is the style, which is unavoidable if you want minimum distortion (if you bend lenses it's much harder to produce a flat image). They are on the heavy side, but I consider that "durable" instead of a negative.
