do you have to choose how much tint if yes what do you recommend
I don't remember. I think you get to choose the color of the tint.
I would choose the strongest.
My only complaint about wearing sunglasses... After a long day and driving and all I tend to get more tireD while wearing them than if I was in my reg glasses 👓.
Usually when I am on very little sleep. That may be a factor as well.
