Everything You Need to Know about Polarised Sunglasses

We’ve all experienced glare in our daily lives.

We can experience glare from looking at screens for too long. Driving at night. Or even looking at bright lights.

But those aren’t the only places where glare can manifest. In fact, glare can intensify during the Winter months.

Whilst Winter eye care is essential for optimum eye health, it’s also important that you invest in polarised sunglasses. Polarised sunglasses aren’t like any other lenses on the market as they work to protect your eyes from blinding glare which can cause permanent damage over time.

What are polarised sunglasses?

In order to understand how polarised sunglasses work, we first need to understand a little bit more about light.

Light reaches your eyes in vibrating waves that moves in all directions. When the vibrations from light waves become aligned in one or more direction, the light becomes polarised and matches the angle of the surface. For example, when you look at the surface of a lake in bright sunshine, you might notice a reflective glare. This is polarised light.

Unlike standard sunglasses, polarised sunglasses are laminated with tiny vertical stripes that only allow vertically angled light to enter the eyes. By wearing polarised sunglasses, glare is eliminated almost immediately as the light waves cannot bypass the vertical filter.

Is there much difference between polarised sunglasses and sunglasses?

You’re probably thinking polarised sunglasses do the same thing as standard sunglasses, but that’s not the case. Standard sunglasses offer basic protection against bright light and UV rays which is why many opticians recommend UV400 sunglasses at the bare minimum. However, these lenses aren’t always able to reduce glare.

Polarised sunglasses block blinding glare and can also enhance visual acuity, colour contrast, visual comfort and blocks 100% of harmful UVA/B light.

What are the different types of polarised sunglasses?

Polarised sunglasses are available in nearly all lens types, materials, coatings and designs. There are two main types – polarised varifocal sunglasses or polarised high index sunglasses. These can be added to any frame type such as rimless glasses.

How can polarised sunglasses protect my eyes during the Winter months?

There are various ways polarised sunglasses can protect your eyes during Winter. They can:

  • Reduce glare from light-reflecting surfaces such as water, glass and snow
  • Improve contrast, visual comfort and acuity
  • Block blinding glare that sunglasses and standard sunglasses would otherwise struggle to block
  • Be particularly useful for people with certain eye conditions that make them more sensitive to light such as cataracts or age-related macular degeneration (AMD)
  • Help prevent eye strain and fatigue
  • Sharpen the contrast between light and dark surroundings

Can I wear polarised sunglasses all the time?

There are certain situations where it’s not a good idea to wear polarised sunglasses. For example, it’s difficult to see LCD screens or displays through polarised sunglasses. People who work in high-risk or critical work (like pilots or machine operators) should avoid wearing them.
