I remembered that these goggles were amazing at blocking sunlight (since they were for protecting sensitive, just-surgeried eyes) and decided to use them as my driving sunglasses
IIRC in Europe it's illegal to drive with sunglasses stronger than [some amount].
I doubt that these are illegal, as they were supposed to be used for driving post-surgery. You had to wear them constantly, and it was ok to drive during that time (after the first 24 hrs or so). In fact, I think they even specifically recommended using them for driving during the first week or so.
I think the main reasons they work so well isn't that they are amazingly dark, but that they completely surround your eyes.
This is the public group instrumental rationality diary for the week of June 4th. It's a place to record and chat about it if you have done, or are actively doing, things like:
Or anything else interesting which you want to share, so that other people can think about it, and perhaps be inspired to take action themselves. Try to include enough details so that everyone can use each other's experiences to learn about what tends to work out, and what doesn't tend to work out.
Thanks to everyone who contributes!
