Drivers are being warned that they are at risk of cancer due to high levels of UV rays coming in through their windows.
A new study by the Boxer Wachler Vision Institute in Beverly Hills suggests that many side windows of automobiles may not offer sufficient protection from ultraviolet A (UVA) rays.
UVA linked to cancer
According to the Skin Cancer Foundation, while UVA radiation is less intense than ultraviolet B (UVB) radiation, it can cause significant damage to the skin’s DNA over time.
UVA radiation is up to 30-50 times more prevalent than UVB and can pass through clouds and glass.
Study author Dr. Brian Boxer Wachler says the level of UVA protection in the windows of automobiles is unclear.
But research suggests cataracts and skin cancer are more common on the left side of the face – the side of the face that is most exposed to sunlight in US drivers.
Low protection on drivers window
Dr. Wachler found that the average UVA blockage on the front windshield of the automobiles was 96 percent, with each vehicle ranging between 95-98 percent UVA blockage.
But UVA blockage in the driver’s side window was much lower, with an average of 71 percent. Side window UVA blockage was also highly variable, ranging between 44-96 percent.
The findings suggest automobile manufacturers should increase their levels of UVA protection in side windows of vehicles.
