I/O's are great.
But check it out like this. If you can take 3 minutes or less to swap a dark lens with a transparent lens, then you have all the versatility in the world. Theres no such thing as a good lens that can be suitable for most conditions.
Hands down the most awesome goggles in the world...
Ashbury Kaleidoscopes, 80 dollars and they come with two lenses (One dark brown, one transparent yellow). They have a thin frame that allows a very wide range of vision and will easily fit well for most faces and nose bridges.
Far better than a 140$ pair of oakleys/vonzippers/electrics/smiths that only come with one lens.
