9/10 times if you have light eyes you can get the medical waiver form from an optometrist. I have one due to being photophobic. (Light sensitivity) my windows are 5% all around, be warned though. Cops get bull**** when you show them the paper and they verify that it's true, if you're not getting a tint ticket, you'll get hassled about exhaust, or lights, or too low, or whatever. Worth the trouble? For me, yea. Tint make the drive more pleasant and makes the car look better. Plus even if they give you a ticket, the medical waiver will get you out of it in court.
