You and me both John but the don't work so well in the car do they?

How do you mean? I can honestly say that I've never had a problem in the car, either with them darkening when I'd rather they didn't, or the other way round.
I don't know which type you have - mine are Zeiss Transitions and they don't go anywhere near as dark as a conventional pair of sunglasses even in bright sunlight, but they do "take the edge off" on a bright day. You don't really notice the effect unless you take them off.
Mine don't go dark when I am inside the car in bright sunlight and I didn't expect them to as I assumed the windows filtered out the light they reacted to.
Outside in the sunlight they go as dark as normal sunglasses.
Are you saying yours change regardless of indoors or outdoors. I was just about to buy some precsciption sunglasses for driving in bright sunlight.
Mine don't go dark indoors, and as Anton points out they don't go nearly as dark inside the car as they would ouside the car, because they react mainly to UV light.
Now that I think about it, I realise why I don't have a sun problem. I am also very tall (6'5") and I sit reasonably upright in the seat in accordance with best practice. As a result I am always looking through the top part of the windscreen and the roofline is a natural sunshade. In the four years I have had my present car, I have never once had to use the sun visors. On the occasions that I have wanted to, the sun has been so low that to do so would have just obscured all my vision...
