What Are Polarised Lenses and Do I Need Them This Summer?

Aug 27, 2024 | Glasses

Sunglasses are a summer staple, but not all shades are created equal. When it comes to eye protection and visual comfort, polarised lenses stand out from the crowd. But what exactly makes them different, and are they a must-have for your summer adventures?

The answer is ultimately, YES! Polarised lenses are absolutely worth the hype, and in this article, we’ll be explaining why.

How do polarised sunglasses work?

Regular sunglasses simply tint the world, reducing overall light intensity. Polarised lenses, however, take things a step further with built-in filters. Imagine light waves like lines – regular light vibrates in all directions.

When light reflects off smooth surfaces like water, snow, or even a car windshield, these waves become more organised, vibrating mostly in a horizontal direction. This creates glare, that bright, hazy discomfort we experience on sunny days.

Polarised lenses act like a gatekeeper, only allowing light waves that vibrate vertically to pass through. This effectively blocks out the horizontal glare, giving you a clearer, sharper view.

Benefits of a polarised sunglasses

Reduced glare

This is the biggest advantage. By eliminating glare, polarised lenses make it easier to see details, reducing eye strain and fatigue.

Enhanced contrast

Blocking glare also improves colour perception, making the world appear more vibrant and objects more defined.

Improved safety

Particularly beneficial for activities like driving or fishing, where clear vision is crucial. Reduced glare minimises distractions and hazards.

Do you need polarised lenses?

The answer depends on your lifestyle and your summer adventures, so consider if the following applies to you!

  • Spending time outdoors: Whether hiking, fishing, boating, or simply relaxing at the beach, polarised lenses will significantly enhance your visual comfort.
  • Driving: Glare from oncoming headlights and reflective surfaces is a major concern. Polarised lenses can make a big difference in driving safety.
  • Sensitivity to light: If you experience eye strain or headaches in bright conditions, polarised lenses can offer significant relief.

Do polarised sunglasses protect eyes from UV rays?

While polarised lenses offer a fantastic visual experience, it’s important to remember that polarisation itself does not block UV rays. Look for sunglasses labelled with “100% UV rating” to ensure your eyes are shielded from the sun’s harmful ultraviolet rays, regardless of whether the lenses are polarised or not. Many polarised sunglasses combine UV protection with the polarisation filter, offering the best of both worlds.
