What’s the Difference Between Polarised Glasses and UV Protection Glasses?

6 May 2021  |  Admin

If you’re choosing a pair of safety glasses, you’ll know hard it is to find the right pair among hundreds of different brands. One of the main factors you will want to consider of course, is the level of protection they offer. Sunlight poses a real threat to those in bright and sunlit conditions, especially as Ultraviolet light (UV) has been proven to cause corneal problems and distorted vision. This can be dangerous for those with jobs based in bright and reflective workplaces.

What Is UV Light?

Invisible to the naked eye, UV light consists of waves of electromagnetic radiation produced by the Sun. There are three types of UV light which are measured in nanometres (nm):

  • UVA Rays: These rays can pass through the cornea and cause cataracts
  • UVB Rays: These can cause corneal issues, distorted vision and “snow blindness”
  • UVC Rays: These are the most harmful of UV rays but they are mostly blocked by the ozone layer

Do You Need UV Protection On Glasses?

Yes, if you work in bright environments, it’s worth wearing a pair of UV Resistant Glasses, which are glasses treated to protect against UV radiation. There are however, other pairs of glasses on the market that provide purportedly similar qualities, specifically Polarised Glasses.

What Are Polarised Lenses?

Polarised lenses are specifically designed to only allow light waves through the lens at a single orientation. Ordinarily light waves come at your eyes from all sorts of angles due to reflections, but polarised lenses align the light coming through. The effect of this is that these types of lenses are able to cut out glare. While this does not make the sun any less damaging to your eyes, but it removes the very harsh points of reflection you see from things like water and glass.
