When you are qualified we send you a list of specifications you can take to any window tint shop so they can narrow down which type of tints you can put on your vehicle based on your medical recommendations.
If you have an existing tint you can take your vehicle to any tint shop and show them these specifications to have them meter the tint on your windows to see if your existing tint meets the medical recommendation requirements.
Having a medical recommendation from a Doctor to have darker window tint does not guarantee you will not get a ticket. An officer can still give you a ticket at their own discretion. However, in our experience with existing customers if you take your ticket to court and provide your medical recommendation documents your ticket can be dismissed.
