Mine are set in Oakley frames. Costly? Yes. Worth every penny? Yes.
As for the LCD remarks - yes there is a very slight issue. It normally deals with the older displays on gas pumps and really old cell phone screens. But how much time is actually spent staring at gas pumps per week. Simply look at them straight on and your good, or take them off for the few seconds required. LCD displays in cars - never had a problem with those type of displays.
