Everything That You Need to Know About Polarized Lenses
Have you ever heard about anti-glare or polarized lenses? They are known to reduce light glare as well as eye strain. With this, they improve vision and safety in the sun.
While working or playing outside we all get frustrated and the harsh rays of the sun can even temporarily make you blind. In such as situation, polarized lenses can provide protection.
What are polarized or anti-glare lenses?
Light typically scatters due to its reflection at different angles of an uneven surface. However, if the surface is smooth, such as with still water or a flat sheet of metal, the light is reflected at a single angle. A glare occurs when this reflected light enters our eyes directly. Polarized sunglasses which have polarized lenses can mitigate this problem by reducing glare.
How do polarized lenses work?
Polarized lenses come with a special chemical that is meant to filter light. The chemical molecules are lined up in order to block some of the light from passing through the lens. You can understand it by thinking about a miniblind hanging in front of a window. You can only see the light that passes through the blind’s opening can be seen.
Polarized lenses in sunglasses use a filter that generates vertical apertures through which only light rays that approach your eyes in a vertical direction can pass. Conversely, all the horizontal light waves that reflect off a smooth pond or a shiny car hood, for example, are obstructed by the lenses.
Due to this filtering, polarized glasses are a bit darker than usual. You can find the polarized lens for sale online at an affordable price and pair them with the frame of your choice. Objects appear crisper and clearer with polarized lenses and allow you to see details clearly.
When should you use polarized glasses?
