Polarised Sunglasses

Polarised Sunglasses

When it comes to sunglasses, you may have come across the term "polarised lenses." But what exactly does it mean? And how do polarised lenses differ from non-polarised ones? Let's dive into the world of sunglasses and explore the differences between polarised and non-polarised lenses.

What are Polarised Lenses?

Polarised lenses are specially designed to reduce glare from reflective surfaces such as water, snow, and glass. They contain a special filter that blocks intense horizontal light waves, allowing only vertical light waves to pass through. This unique feature helps to enhance visual clarity and reduce eye strain.

How Do Polarised Lenses Work?

Polarised lenses work based on the principle of polarization. When light reflects off a surface, it becomes polarised, meaning the light waves align in a specific direction. This polarised light can create intense glare, making it difficult to see clearly. However, polarised lenses counteract this glare by blocking the horizontally polarised light waves, resulting in a clearer and more comfortable vision.

Benefits of Polarised Lenses

1. Reduced Glare: The primary advantage of polarised lenses is their ability to reduce glare. Whether you're driving, fishing, or participating in outdoor activities, polarised lenses can significantly enhance your visual experience by eliminating blinding glare.

2. Improved Visual Clarity: By reducing glare, polarised lenses enhance visual clarity and sharpness. They allow you to see objects and colors more accurately, providing a more vivid and natural view of the world around you.

3. Better Eye Comfort: Glare can cause eye strain, fatigue, and even headaches. Polarised lenses help alleviate these issues by blocking the harsh light that causes discomfort, allowing you to enjoy your time outdoors without unnecessary eye strain.

Non-Polarised Lenses

On the other hand, non-polarised lenses do not have the special filter that blocks horizontal light waves. While they still provide protection against harmful UV rays, they do not offer the same level of glare reduction as polarised lenses.

When to Choose Polarised Lenses?

Polarised lenses are particularly beneficial in certain situations:

- Water Activities: Whether you're boating, fishing, or enjoying a day at the beach, polarised lenses can help you see beneath the water's surface, reducing glare and allowing you to spot fish and other objects more easily.

- Driving: Glare from the road and other vehicles can be distracting and potentially dangerous. Polarised lenses can improve visibility and reduce eye strain, making driving safer and more comfortable.

- Outdoor Sports: If you're an avid golfer, cyclist, or runner, polarised lenses can enhance your performance by providing a clearer view of the terrain and reducing glare from the sun.


Polarised lenses offer numerous benefits, including reduced glare, improved visual clarity, and enhanced eye comfort. Whether you're engaging in water activities, driving, or enjoying outdoor sports, polarised lenses can make a noticeable difference in your overall visual experience. So, the next time you're shopping for sunglasses, consider opting for a pair with polarised lenses to enjoy the advantages they bring.
