Get ready to step into a world of reduced glare, improved clarity, and enhanced eye protection as we dive into the captivating realm of polarised sunglasses.

What are Polarised Sunglasses?

Polarised sunglasses are more than just a fashion statement; they are specialized eyewear designed to reduce glare and provide better vision in bright and sunny conditions.

Unlike normal sunglasses, polarised lenses contain a unique filter that blocks horizontal light waves, allowing only vertical light waves to pass through. This advanced technology helps eliminate reflections from surfaces like water, glass, and snow, ensuring clearer and more comfortable vision.

How Polarised Sunglasses Work

Polarised lenses consist of a special chemical film that acts as a microscopic filter. When sunlight bounces off flat surfaces, it becomes horizontally polarised, causing glare and visual discomfort.

The polarising film in these sunglasses absorbs the horizontal light waves, effectively neutralizing glare and enhancing visual clarity.

Let's look at some of the pros and cons of using a polarised sunglass.
