Ultraviolet rays or UVB are very different things – and the glasses only block one of them. But the car and a house window also have differences.
Of the total UV (Ultraviolet) radiation that hits the land, about 95% is grape and 5% is UVB. Although less and only reaching the upper layers of the skin, UVB are very dangerous – they are mainly responsible for skin cancer, burns and even cataracts.
Now, when we go in a car sunbathing on the arm, for example, we notice that we are tanned. However, all glasses used in the windows of houses, offices and cars completely block the passage of UVB rays.
That is, what comes to the glass is the UVA rays, never the UVB. However, these rays can also be quite harmful to the skin and cause burns. That is, in general, the answer to the question about if the sun we catch by the glass can burn to the point of a scalding, the answer is sim. But it’s not that simple, explains the.
The front windshield of a car lets in a lot of light and sun. However, blocks 98% of grape radiation, Since it consists of two layers of laminated glass, the only type of glass that does not let these UV rays enter.
But what about the side windows of cars? These are already made of tempered glass, and one carried out in 29 cars revealed that between 4% and almost 56% UVA rays passed through the side and rear windows.
However, if the glass is smoked, it has some kind of paint or protective film, it will be saved. THE smoked glass blocks about 95% of grape radiation, concluded another, 2023.
In fact, the Skin cancer is more common on the conductor side. An American (country where drivers sit on the left) detected more skin cancers on the left than on the right side on the face, scalp, arm and leg, including 20 times more on the arm, which allows you to concludeRa exposure to the sun through the car windows is harmful.
At home or at work, most of the glasses used in residential windows let a large amount of grapes passbetween 45 and 75%. Only the skylights, made of laminated glass, are safe from these rays.
Most glasses of Office windows has better grape protection than residential windows, allowing less than 25% grape transmission.
Next to lunch time, if a house window is near that allows for more grapes, It may take only 30 minutes to burn In summer and only an hour in winter.
