I am assuming you don't wear transitional lenses? I'd figure if they turn into sunglasses, one would be considered even more scary?
Those transitional glasses are the biggest scam ever. I bought a pair last Spring and long story short took them back a week later and got new ones.
They would darken in any outdoor light, meaning if there was dark clouds they would still darken and I could barely see. Then, when I would go inside a restaurant or store, just on the walk from my car to the door they would darken and once inside would take a good 2-5 minutes to change back to normal (depending on the light levels inside)..the most fucking annoying they I have ever had. Plus, if you look at yourself in the mirror when they have changed, you look like a fucking freak..I don't know who it was but someone in the Yankees organization used to wear those and when they would pan to him on tv he would look fucking retarded, because the dark part was so small..it was like he was wearing 1/3 size sunglasses. That was the same way it was for me.
Transitional lenses are evil.
