Scott Sutherland a Meteorologist with theweathernetwork.com wrote about the video that is here below. It is from photographer Thomas Leveritt, who threw a filter in front of a camera lens, so that it would only pick up the ultraviolet light being reflected off everything in the cameras' view.
Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light but longer than X-rays. It carries the color name Violet because the spectrum consists of electromagnetic waves with higher frequencies and shorter wavelengths than those visible to humans as the color violet.
When you look at individuals around you with such a filter the complexions you see are unlike the smooth and healthy they appear to your normal vision.
When we become aware of ultraviolet light, it's always about the three types – UVA, UVB and UVC – ranging from least energetic to most energetic, thus least harmful to most harmful. UVC is so energetic that it can in fact kill living cells.
The ozone layer Life on Earth outside of the deep oceans is possible only because the atmosphere, primarily the ozone layer, and oxygen molecules in the environment take care or filters out a substantial majority of UVC, so usually none of it reaches the ground.
The ozone layer also blocks many of the UVB spectrum, so just the longest wavelengths of those make it through, and it's mainly those and the diversity of UVA wavelengths that reaches us here on the ground.
While those wavelengths that reach us aren't immediately dangerous, and they can even promote the production of vitamin D in our bodies, they can still cause damage to our skin – UVB specifically, but also UVA with sufficient direct exposure to it. We tan. We burn. We freckle. After years, it can all amount to a great deal of damaged skin cells. This can lead to skin cancer, however even if it does not, the adverse effects add up.
That's what Leveritt's camera is showing us. All of the freckles and dark patches that show up with the UV filter in place are damaged parts of our skin that do not reflect UV light anymore.
The striking part is when Leveritt provides the people sunblock to put on their face. Sunblock takes in UV light, as opposed to reflecting it or or allowing it through. So, to the camera it looks like they are rubbing ink into their skin.
At the minimum, this is just a remarkable look at what an easy change in our point of view can show us. However, at the very same time, it also goes to show how covering up and wearing sunscreen is most likely an excellent preventative concept, especially on high UV Index days, and how it's an actually good thing that the world had the ability to come together for the Montreal Protocol, to prevent our ozone layer from being completely deteriorated away.
The complexions you see may appear to be smooth and healthy, but if your eyes could see into the ultraviolet end of the light spectrum, you could see a very different story.
When we hear about ultraviolet light, it's always about the three types – UVA, UVB and UVC – varying from least energetic to most energetic, therefore least destructive to most destructive. The ozone layer likewise obstructs many of the UVB variety, so only the longest wavelengths of those get with, and it's mostly those and the variety of UVA wavelengths that reaches us right here on the ground.
While those wavelengths that reach us aren't immediately dangerous, and they can even promote the production of vitamin D in our bodies, they can still cause damage to our skin – UVB particularly, however likewise UVA with enough direct exposure to it.
The Montreal Protocol on Substances that Deplete the Ozone Layer (ODS) was agreed upon in the framework of United Nations to minimize the production and consumption of ozone depleting elements in order to minimize their abundance in the environment, and therefore secure the earth's delicate ozone Layer. The initial Montreal Protocol was agreed on 16 September 1987 and entered into force on 1 January 1989.
The Montreal Protocol includes special adjustment arrangement that allows the Parties to respond rapidly to new scientific information and accept to increase and decrease chemicals already covered by the Protocol. Since its preliminary adoption, the Montreal Protocol has been adjusted 6 times for specific modifications and decreases of production and consumption of the regulated chemical compounds.
The Parties to the Montreal Protocol have amended the Protocol to allow, among other things, the control of brand-new chemicals and the creation of a monetary mechanism to enable countries to comply.
Joint efforts between firms, private companies and governments, and between the governments themselves are all contributing to the success of the ODS replacement process.
Now the battle againt skin cancer is not getting the results expected because people insist in exposing themselves to too much solar radiation or not doing what is neccesary to reverse the damage and repair DNA.
Nowadays there are natural skin care products with ingredients that penetrate into the dermis and at the junction of the epidermis and the dermis where the fibroblasts reside and make all the structural components that regenerate skin periodically. There they help to repair DNA of aging fibroblasts. One such ingredient is snail secretions as they are included in Bioskinrejuvenation, a natural skin care product for skin rejuvenation, age spots or uneven skin tone, that also strengthens the skin so that is functions much better. This skin rejuvenation product that removes age spots, hyperpigmentation and uneven skin tone is also available at amazon.com
