Sunglasses: The Pros and Cons of Polarised Lenses | Loxley Opticians

Polarised lenses: Everything you need to know!

Polarised lenses and glare

Before we dive into the details of polarised lenses we need to address Glare.

So what is it? Glare is the horizontal reflection of light. Put simply, it’s where bright or reflected light can affect our ability to see or is uncomfortable to look at (think about the blinding light that reflects off the road surface when it’s been raining on a sunny day.)

Not Ideal.

A popular choice

Polarised lenses are arguably the perfect choice when you want to get rid of glare and have full UV protection without compromising clarity and colour perception.

Polarised lenses don’t just reduce glare, they cut it out completely. It therefore comes as no surprise that polarised sunglasses are the first choice for sports athletes around the world, where optimal vision is the priority.

So how do they work?

These lenses have a special filter that only allows vertical light through, which ultimately works to eliminate the horizontal reflection (glare).

A good analogy would be to compare them to a pair of venetian blinds. We’ve all seen how light passes through blinds when the slats are turned from their closed position. The blinds allow the vertical light to come through, but eliminates the horizontal light or glare. We can still see outside because we’re looking over the slats- similar to the polarised technology.

The process in eliminating the reflective glare can help reduce eye strain fatigue while improving colour saturation and increasing contrast.

A breakdown: Pros

  • Cuts out Glare COMPLETELY.
  • Can minimise eye strain and fatigue.
  • No compromise in clarity.
  • No distortion of colours
  • Enhanced comfort: Without the constant battle with glare, your eyes can be in a more relaxed state, and are able to see objects more easily in brighter conditions.
  • Reduces the effect of UV-A and UV-B rays by 100 percent- In other words they provide full UV protection.

What about the cons?

  • They’re more costly than tinted lenses.
  • Polarised lenses make it difficult to view LCD screens- Although you can still see them when you have a direct line-of-sight, moving to different angles can make the screen disappear completely due to the filtering process.

In summary...

The pros and cons of polarised lenses however are typically more about one’s personal preferences: Some people prefer to wear them for the added clarity they receive when outside, while others prefer custom tints to add a pop of colour.

But if we’re being honest, most people who have polarised lenses say they would never go back!
