How and Why are UV Rays Harmful?

Ultraviolet light which we call UV rays is a form of electromagnetic radiation whose wavelength falls between that of visible light and X-rays. While most UV rays come from the sun, it can also be found in specialised lights such as black lights or tanning beds. The same process that can give your skin a toasty tan in the middle of winter can also wash the colour out of your drapes or turn your furniture blotchy in appearance.

How does that happen? UV rays cause chemical reactions with objects that they touch, causing many of them to glow, just like those black light posters in your old dormitory room at school. That chemical reaction is permanent though, so once the drapes or an oil painting on your wall has reacted to UV radiation you can’t bring it back to the original. This is why art galleries don’t hang their paintings by un-tinted windows!

The physical danger to our bodies from long-term exposure to UV rays is also severe. There is proven medical evidence linking UV exposure to skin cancer and even DNA damage. Our skin actually develops a tan as a defensive shield to try and block Ultraviolet radiation.

Our eyes however do not tan. Therefore, sudden or long-term exposure to UV light can lead to what is known as ‘welder’s eye’ as well as cataracts and other forms of damage to the cornea, lens and retina. That’s why you never look at the sun during an eclipse; that’s why tanning booths make you wear those funny plastic goggles.

Your best protection for your home and your eyes for day-to-day use is to protect both by installing window tints that will block up to 99% of the harmful UV radiation. It just makes sense. Call Ultimate Tinting today for a free estimate on protecting your Auto, Home or Business.
