Car window tinting is a relatively new fad that is actually quite a practical investment. Before car window tinting people drivers would have to shade their eyes from the sun with hats, visors, or sunglasses; and then when the car is parked, put up massive shades to protect the interior from getting too hot.

Indeed, automobile windshield and window tinting has really helped to improve the comfort and longevity of many vehicles.


But there is a bigger reason for Autoglassexperts.ca tinting the windows of your car—yes, bigger than comfort and longevity. Even bigger than simply “looking cool.”

ULTRAVIOLET RADIATION

Every single sunbeam carries in it ultraviolet radiation. UV, as it is often called, is “light” that we cannot see. It can penetrate solid objects and even the skin.  While it is not dangerous in small amounts, too much exposure can be bad for your health.

A CLOSER LOOK

There are actually three classifications of UV radiation.  These are, as you could probably discern: UV-A, UV-B, and UV-C.  UVA is the longest of the three ultraviolet radiation wavelengths; keep in mind that all UV radiation is on a shorter wavelength than sunlight, and that is why we cannot see them.  UVA measures between 320 and 400 nanometers; keep in mind that a nanometer is one-billionth of a meter.  And there are two wave ranges of UVA.  UVA I measures between 340 and 400 nm while UVA II measures between 320 and 340.  UVB, which only has one range, measures between 290 and 320 nm. UVC is the smallest of the three (below 290 nm) and is typically reabsorbed into the atmosphere before reaches the surface of the earth.  

UVA and UVB RISK

As you might have guessed, we need not concern ourselves with UVC.  It rarely makes it far enough into the atmosphere to be of any consequence to human health. UVA and UVB, however, are the ranges you need to be concerned about.  These are the two ultraviolet ranges associated with skin cancer (and other cancers, actually).  Studies also show that UVA and UVB are both able to suppress the immune system.

UVB AND YOUR SKIN

If you have ever had a sunburn, you have UVB to thank. The UVB range is generally the cause of heat rash and sunburn.  Moderate exposure, of course, can be very healthy, though, so there is always a delicate balance.
