What Are Polarised Sunglasses And How Do They Work


Polarised sunglasses are known for blocking glare reflected from some surfaces for you to have a unique sunglasses experience. They are very effective at enabling you to see smooth, reflective surfaces such as water, snow, roads or glass, which is one of the reasons for their popularity among people who spend a lot of time outdoors or engaged in so many outdoor sporting activities. 

Polarised sunglasses are not only for people who love engaging in activities that involve water, like boating and fishing; they are meant for anyone worried about glare who can make use of it. Polarised glasses are the best type of glasses for those whose eyes are susceptible to light, and they're suitable for driving. 

What are The Benefits of Polarised Sunglasses?

There are some benefits you will derive from using polarised sunglasses, and some of them are 

  • Excellent glare control in water areas or reflecting surface 
  • Better vision while driving
  • More vibrant colours and contrast in nature
  • Improved visual clarity, contrast and sharpness
  • Improved dept colour  perception
  • Eliminate eye fatigue and increase eye comfort

The best way to reduce the risk of eye fatigue caused by the glare entering your eyes is by using polarised lenses. Apart from protecting your eyes from UV rays coming from the sun, it would be best if you saved them from glare too. 

Exposing your eyes to the glare from the sun can lead to you having eye strain, and exposure to the glare for too long can lead to temporary blindness. 

If you are the type that drives for a very long period, these glasses should provide you with more comfort and clearer vision

Benefits Of Polarised Glasses

On many occasions, people complain of getting tired of engaging in outdoor activities quickly due to their long time batting with glare. Still, reports have gathered that they feel less tired when wearing their polarised sunglasses. Polarised sunglasses are suitable for almost all outdoor activities but are extremely helpful in the following: 

  • Fishing: People who engage in fishing activities using a polarised lens have found that it dramatically reduces glare and helps them see underwater.

  • Boating: Water can reflect the light rays from the sun, which can cause glare. Staying on the water for a long while boating can result in eye strain due to the glare but using polarised glasses helps you to see more clearly and prevent eye strain. 
  • Golf: Polarised lenses help golfers in reducing the glare on the fairways, and it allows you to spot your golf ball easily, especially when it hits a water hazard 
  • Driving: When the sun's intensity is high during driving, there is a high chance of the reflection on the road getting into your eyes, which may cause an accident because you won't be able to see clearly. A polarised lens will filter the reflected light and enable you to see more clearly. 

When you find yourself in a snowy environment, it is also essential for you to have your polarised glasses on because the glare that snore or ice produces is higher than the one water surface makes.

Apart from the UV rays from the sun, you should also guide your eyes against the glare it produces when it shines on a reflective object. The glow can increase your chance of developing short- and long-term eye defects. 

One of the long-term defects is cataracts. The glare from these reflective objects will continue to damage the eye cells. Apart from these, other effects that glare can cause includes headache, temporary blindness, sunburn and so on.

When your glasses lenses are polarised, you will rest assured that your eyes are fully protected from all possible damage the sun can cause to your eyesight.

    How to Tell if Your Sunglasses are Polarised

    There are three ways you can test if your polarised lens is authentic. First, the anti-glare technology on the lenses has a unique property different from non-polarised sunglasses. You can try the lens using a reflective surface or computer screen to compare with your other none polarised sunglasses. 

    • Test your polarised lens on a reflective surface

    Look for anything that produces a reflection of light rays around you, like a mirror or shining floor tiles. Ensure the glow is evident from about half to one metre away. If the glare is not enough, you can use an artificial light like a lamb or a touch light on the surface to produce more glow. Then hold your glasses a little bit away from your eyes, up to 20 cm, then rotate them at an angle of about 60°. Then look through the lens; you should see a notable difference. If you have a polarised lens, the glare will reduce drastically or disappear, but if not, the glasses with you are not polarised sunglasses. 

    • Comparing it with a pair of non-polarised  sunglasses 

    Another method of knowing if your sunglasses lens is polarised is by taking a none polarised sunglasses with you when trying to get a polarised one. Place the two sunglasses close to each other and look at a glare through them. It would help if you spotted the difference instance because the glow won't pass through the polarised lens but will pass through the no polarised lens.

    • Using Your Computer Screen 

    The third method you can use is making use of your computer screen. The first thing is to turn on your computer to ensure it is at's brightest level, and to make the test more effective; you can open a white background. After that, put on your polarised sunglasses and look directly at your computer system screen. Try to tilt your head a little to the left or right. If the sunglasses are polarised, you should notice a blue-black colour while looking at the screen, and if not, that means the glasses are not polarised sunglasses.   


    Test the polarised sunglasses before making purchases. You can take a phone with a flashlight to test its polarity or get your sunglass from a standard store with a polarisation test card to be assured that you are buying a genuine product. 

    Protecting your eyes from UV rays is an excellent idea, but you still have to ensure that the glare from the reflective surface around you does not damage your eye health. To protect your eye fully, it is best to use polarised lenses that will give you reasonable protection from glares and clearer vision.
