Polarised glasses


Whether relaxing at the beach, enjoying a hike or going for a drive in the sun, it is important to protect your eyes and give yourself the best vision possible. You may have heard of polarised lenses before but do you know…

What is polarisation?

What are the benefits of a polarised lens?

POLARISATION is a filter within the lens that neutralises glare bouncing off other objects. Distracting reflections from a body of water, glare from wet roads or reflections off windshields would all be reduced with a polarised lens.

Similar to a venetian blind, light in one direction is controlled and it is this act that is the basis of polarisation and minimising the annoying glare.

What are the benefits of a Polarised lens? 

Polarised lens’s unique ability to cut horizontal glare means they provide excellent clarity and comfort even in very bright conditions.

Benefits include:

  • Reduced glare off surfaces – for example a wet road or river/lake/sea
  • Reduced symptoms of eye strain
  • Increased contrast and vibrancy of colours

Who should wear polarised glasses?

 EVERYONE! But a polarised lens is especially beneficial when…

IN THE CAR: Dazzling light from oncoming traffic and shiny wet roads can make driving troublesome and even dangerous. You don’t have to be behind the wheel – passengers also have the effect of glare off the wet road surface.

PLAYING SPORTS:  By reducing glare, increasing contrast and enhancing colours players are given the best vision to aid their performance allowing them to react quickly. Polarised glasses are also commonly worn by golfers, cyclist and runners.

ON THE WATER: For those interested in water sports like fishing, sailing or surfing polarised lenses can be especially helpful to see across the blinding bright water. It eliminates the sheen on the surface and allows you to see through to the water below.

Polarised lenses are particularly beneficial for people who are:

LIGHT SENSITIVE: Various eye condition such as cataracts, age related macular degeneration (ARMD) or Uveitis (a type of inflammation to the eye) can cause discomfort with bright shiny lights. The reduction of glare from polarised lenses can help relieve symptoms of bothersome glare and eye strain.

POST SURGERY: After eye surgery some people will experience difficulty with glare. It is advised to wear a pair of polarised sunglasses in order to ease recovery so you do not have to deal with the harshness of the glare.

When are polarised lenses not appropriate?

WHEN USING LCD SCREENS: Polarised lenses neutralise light in the horizontal axis which means professions or hobbies that require the regular use of LCD (liquid crystal display) screens, such as a pilot should not wear polarised lenses. Polarised lenses will dim down screens and make it more difficult to see details.

NIGHT DRIVING: When driving at night or in low light conditions.

Prescription Glasses:

Polarisation can be added to most prescription sunglasses.
