What are the various lens types that you might come across? Polarised and non-polarised lenses are the two types that you will majorly have to choose between. While both polarised and non-polarised lenses offer shade from harsh sunlight, there are a lot of differences between the two types. What are polarised lenses for sunglasses? To understand polarised sunglasses better in detail, you must read ahead. In this article, we will be sharing with you all the information that you need about polarisation and polarised lenses to help you choose the right lens type for your sunglasses.
To understand polarization, you will have to understand a little about the nature of light and how light travels. Light travels in reflected waves. Non-polarised light is light that reflects in more than one direction or more than one plane and polarised light waves are waves that reflect in a single direction and single plane. Light can travel in vertical and horizontal directions. Of these, light travelling in a horizontal direction is highly problematic. This light creates unwanted and dangerous glare by reflecting from various surfaces. This is where polarised lenses for sunglasses come into the picture and are useful for the wearer.
Polarised lenses take in the non-polarised light or the light waves coming in from all directions and in various planes to filter them and convert them into polarised light which travels in one direction and in a single plane. This ensures that the light entering your eyes will not cause any major disturbances to your vision.
Both polarised and non-polarised lenses for your sunglasses help in protecting your eyes from the two types of UV rays- UVA and UVB and bright light. Then why is there the need to choose polarised lenses for your sunglasses? Let us take a look at the following section to understand the same.
