by Bulltru Sunglasses 18 Jan 2024

In this article, we will discuss techniques on how to tell if sunglasses are polarized and why having them is imperative. When it comes to shielding our eyes from the harsh rays of the sun, sunglasses are an essential accessory that we cannot do without. However, have you ever come across polarized sunglasses? The designers specifically crafted these special sunglasses to diminish glare and offer enhanced clarity in bright conditions.

Polarized sunglasses have a unique feature that sets them apart from regular sunglasses - they contain a special filter that blocks out horizontal light waves, which are responsible for creating glare. This filter helps to enhance visual comfort and reduce eye strain, making polarized sunglasses a popular choice for those who spend a lot of time outdoors.

Why choose polarized sunglasses?

Now that you know what polarized sunglasses are, you might wonder why you should choose them over regular sunglasses. Well, several benefits make polarized sunglasses an excellent choice for anyone who wants to protect their eyes and enjoy clear vision.

Look no further if you're wondering how to tell if sunglasses are polarized. Polarized sunglasses offer exceptional glare protection, making them essential for various outdoor activities like driving, fishing, and more. Surfaces such as water, sand, or snow can often produce intense glare that can be both distracting and hazardous. However, polarized sunglasses effectively block out this glare. Not only does this provide you with clearer vision but it also reduces the strain on your eyes, ensuring a safer and more comfortable experience.

Secondly, polarized sunglasses enhance visual clarity. These sunglasses improve contrast and color perception by reducing glare, making your surroundings appear more vibrant and sharp. This can be especially beneficial when skiing, boating, or playing sports, where precise vision is essential for optimal performance.

Polarized sunglasses offer more than just style! They provide added UV protection, just like regular sunglasses. In fact, the polarized filter in these sunglasses not only blocks out annoying glare but also shields your eyes from harmful UV rays. By reducing the risk of eye damage and conditions like cataracts and macular degeneration, polarized sunglasses are a smart choice for anyone seeking optimal eye protection.

Benefits of wearing polarized sunglasses

Now that you understand why polarized sunglasses are a great choice, let's dive deeper into their benefits.

  1. Reduced glare: As mentioned earlier, polarized sunglasses effectively reduce glare from reflective surfaces, allowing you to see more clearly and comfortably. Whether you're driving on a sunny day or spending a day at the beach, polarized sunglasses can significantly enhance your visual experience.
  2. Improved safety: Glare from the sun can be a safety hazard, especially when engaging in driving or water sports. Polarized sunglasses help to eliminate this glare, making your surroundings more transparent and reducing the risk of accidents.
  3. Enhanced visual comfort: Polarized sunglasses provide enhanced visual comfort by reducing eye strain and fatigue caused by glare, allowing you to enjoy your time outdoors without squinting or straining your eyes.
  4. Better color perception: The polarized filter in these sunglasses improves color perception by enhancing contrast and reducing color distortion. This means you'll be able to see colors more accurately and enjoy the beauty of your surroundings to the fullest.

Overall, wearing polarized sunglasses offers a more enjoyable and safer outdoor experience, making them a must-have accessory for anyone in the sun.

How to Tell if Sunglasses Are Polarized

The Water Test

Performing the water test will determine if sunglasses are polarized. Here's how you can do it:

  1. Find a reflective surface, such as a lake or a car windshield, to observe the glare.
  2. Put on the sunglasses and look at the reflective surface.
  3. Tilt your head to the side and observe the glare. If you tilt your head, the sunglasses are likely polarized if the glare reduces or disappears.

This test works because polarized sunglasses block out horizontal light waves, which are responsible for creating glare. By tilting your head, you change the angle at which the light waves reach your eyes, effectively reducing the glare.

The Glare Test

Another way to determine if sunglasses are polarized is by performing the glare test. Here's what you need to do:

  1. Find a reflective surface with a bright light source, such as a car hood or a glass window.
  2. Put on the sunglasses and look at the reflective surface.
  3. Slowly rotate your sunglasses while keeping your eyes on the glare. The sunglasses polarize if the intensity of the glare decreases or disappears at certain angles.

To understand how to tell if sunglasses are polarized, it is important to know that these specialized eyewear is specifically designed to reduce glare. When you rotate a pair of polarized sunglasses, the lens filter adjusts in such a way that it blocks out horizontal light waves, which are the main culprits behind glare. As a result, the intensity of the glare decreases or even disappears completely at certain angles.

The LCD Screen Test

Suppose you don't have access to water or a reflective surface. Using an LCD screen, you can still determine if sunglasses are polarized. Here's how:

  1. Find an LCD screen, such as the one on your smartphone or tablet.
  2. Put on the sunglasses and hold the screen in front of you.
  3. Tilt the sunglasses at a 60-degree angle and look at the screen. The sunglasses are likely polarized if the screen appears darker or even completely black.

LCD screens emit polarized light, and when you look at them through polarized sunglasses, the lens filter blocks out the polarized light, causing the screen to appear darker or black.

Other ways to test if sunglasses are polarized

Water, glare, and LCD screen tests are the most reliable methods to determine if sunglasses are polarized.

  1. Double reflection test: Hold the sunglasses in front of your eyes and look at a reflective surface. If you see a double reflection, it means the lenses are polarized.
  2. Color distortion test: Look at a colored object through the sunglasses. If the colors appear distorted or altered, the sunglasses are likely polarized.
  3. UV light test: Take the sunglasses to a store that sells UV flashlights and ask them to shine the light through the lenses. If the lenses block out the UV light, they are polarized.

Remember, these tests can still indicate whether the sunglasses are polarized, but they are not as foolproof as the water, glare, and LCD screen tests.
