What is Polarised light and Glare?
When light reflects off a smooth, reflective surface, it goes through a process called polarisation. The light waves literally ‘polarise’ on a plane – they all travel in the same direction (parallel). This intensifies the rays, making harmful rays even more harmful. This process produces disturbing optical ‘noise’ or simply put, glare. Glare reduces your colour and depth perception and causes eyestrain. Much of the light around us is already polarised. Mirror-like reflections from shiny horizontal surfaces, such as roads, snow, sand and water consist largely of light that has been horizontally polarised in the process of reflection. Polarised lenses, with their transmission axis set vertically, block the horizontally polarised light reflected from road surfaces. How does Polarisation work? Polarisation filters work like mini Venetian blinds, to cut out the organised light and let the random light through the lens, to eliminate glare and reduce eye fatigue. In simple terms, the polarisi
