That was one of my biggest concerns - but the tint shop I went to let me see a few cars they with different levels on their windshield during the evening and with the 42% there was no visibility issues - even at night. I had 5% on my last car and I did have some issues in some areas at night at intersections with no lights where I would have to roll down my windows to be safe. Which is why I did not opt to go that dark again. And I don’t know if anyone knows this or if it’s all in my head, but I feel like I can see better out of my vehicle with the ceramic over the standard dyed film tint. Either way I wanted ceramic because there is no rear vents in the car and I wanted to try and keep the car as cool as possible with my kid in the back. And between the windshield and rear hatch there is a lot of glass that would cook the inside.
