Shield Yourself From The Death Star!

Shield Yourself From The Death Star

Living in Australia, we are very aware of the need to protect ourselves against the harmful effects of the sun, but how does the light actually damage our skin?

Light is made up of visible and invisible components and it is the short wavelength light in the ultra-violet component (UV light) that causes the trouble. In turn this UV light is subdivided into UVA, UVB and UVC depending upon the wavelength. The most powerful of these is UVC, which is filtered out by the earth’s ozone layer and so poses no threat.
