I haven't noticed to be honest. As far as I remember they're pretty transparent. I'll have to take a look in the morning, that's one of those things I can't quite remember because I've never really noticed before haha.

 

On my way to work I actually paid attention to it lol, it is transparent when sitting still, but you obviously lose some of that clarity when moving. These don't add to the A-pillar blind spot since they're so thin, they follow the lines of the window perfectly. When you're in the cab, you only see about an inch of it since the door panel/weatherstripping hides the rest of it from the inside view.

 

Thanks
