I was blown away by the difference. While I was waiting for them to arrive I was dimming my lights. I put them on and opened the doors and though shit I left the lights dimmed. Nope these glasses are just that good! My $20 vivosuns are just sunglasses I think. And they were so wide that I had to put window weather seal on each arm so I could wear them. They wouldn't go behind my ears, I'm not sure who they were made for, I giant I guess.
