Protecting your skin against UVA rays while in the car.

Protecting Against UVA Rays in the Car

In most cars, windshields block almost all UVB and approximately 50% of UVA rays. However, side and rear windows are often clear glass, which does not prevent UVA rays from penetrating.

UVA Rays

UVA rays are responsible for aging skin, precancers, and skin cancers

Blocking Harmful Rays

Patients with sun sensitive dermatoses like lupus and all melasma patients are encouraged to tint the side windows of their vehicles to reduce UVA exposures to 15%-30%. Tinting, however, must be in compliance with federally mandated standard of 70% minimum visible light transmittance. Clear tints often work very well.

Missouri Window Tint Laws

Vehicles registered in Missouri are allowed to have the windows to the immediate right and left of the driver tinted to 35%, plus or minus 3% or more light transmittance. The windows behind the driver and the rear glass are not subject to tinting limitations. For Missouri drivers requiring additional protection from the sun, drivers can apply for a window tint permit from the Missouri State Highway Patrol with a physician’s prescription indicating that a serious medical condition exists and a specific tint percentage is needed above the standard allowance.

It’s important to take the steps everyday to protect your skin. Adding window tint to your car is one way that you can limit the penetration of dangerous UVA rays.  Call George Dermatology today to learn more about how you can protect your skin from the damaging effects of the sun & get inspected by our Board Certified Dermatologist.

What Our Patients Are Saying

Dr Katherine M. Moritz is the bomb-diggity!!! She’s very professional, kind, and most of all caring for my concerns and needs. Today, I walked out of her office with my son in my arms in tears of joy. She removed a cyst on my eyelid that had been there for over a year now. In a matter of seconds, she painlessly had it removed. When I looked in the bathroom mirror, I ran back into her office thanking the staff and giving her my gratitude and thanks. I swear, I cried when I got into my car all over again. This place is a whole vibe, they are culturally competent, and she’s helping me live my wishes in my 40’s, that I had in high school. Dr. Moritz is like the fountain of youth, she’s reversing my aging and I feel more confident in myself than I did in my 20’s.
