What are polarised lenses and how do they work?

Light reflected from surfaces such as water, snow or other smooth surfaces is polarised and spreads only as horizontal and vertical waves. This means that, instead of light being scattered in all directions in more usual ways, reflected light generally travels in a more horizontally oriented direction. This creates an annoying and sometimes dangerous intensity of light that we experience as glare.

Our Polarised lenses contain a special filter that blocks this type of intense reflected light, reducing glare. The filter is created by heating and stretching a film over the lens resulting in the molecules becoming arranged in parallel fibres.

Our polarised lenses are made from a material called CR-39. It has high abrasion resistance, in fact the highest abrasion/scratch resistance of any uncoated optical plastic. Our CR-39 lenses provides very little distortion in fact less than any polycarbonate lenses. It is more lightweight and thinner than glass making it comfortable to wear all day. Other high performance features of our lenses include being more impact resistant than glass and more scratch resistant than polycarbonate.
