Protecting your eyes from harmful ultraviolet (UV) rays is just as important as protecting them from impact
Ultraviolet rays are invisible waves of electromagnetic radiation produced by the sun. They are transmitted in waves towards the earth's surface and form part of the electromagnetic (light) spectrum. UV rays are invisible to the naked eye with wavelengths shorter than that of visible light, but much higher energy levels.
UV is made up of 3 types of rays, UVA, UBV and UVC depending on the frequency of the waves. UVC rays have the highest energy levels with wavelengths of 100-280 nanometer (nm) but are absorbed by the earth's protective ozone layer. Both UVA and UVB rays penetrate the atmosphere and can cause conditions such as premature skin ageing, eye damage (including cataracts) and skin cancers.
UVA rays (320–400 nm) can pass through the cornea and reach the lens and retina. Overexposure has been linked to the development of certain types of cataracts.
UVB rays (280–320 nm) are partially filtered by the ozone layer but some still reach the eye. They can cause corneal problems, distorted vision and a painful condition called 'snow blindness'.
UVC rays (100–280 nm) are potentially the most harmful to your eyes and skin but fortunately the atmosphere's ozone layer blocks virtually all UVC rays.
Protecting your eyes with uvex
Even though our eyes are equipped with their own defence system, this alone is not enough to protect them from harmful UV rays. Reflexes like squinting and pupil dilation are only triggered by the sun’s visible light, meaning on cloudy days the amount of UV light reaching your unguarded eye can be dangerous. All uvex safety glasses offer 100% UVA, UVB and UVC protection.
The name uvex stands for ultraviolet excluded uv-ex.
UV light isn’t part of the visible light spectrum, so blocking UV rays is different to needing a shaded lens on a bright sunny day. Wearing the right safety spectacles will give your eyes the extra protection they need to filter out the dangerous UV rays in sunlight, protecting your eyes for years to come.
