I'm not sure how much of a blue light they block, but I feel the difference.
After all day of driving in gray weather I used to be tired as hell but after I started wearing these, day long driving is not a problem anymore.

I've searched a bit about the orange and yea they block even more blue light. Also the red lenses.

The professional coated glasses are obviously the best you can get, but these colored ones are a great cheap alternative costing you no more then 3 to 15€
