To ensure the authenticity and adherence to the safety standards of your sunglasses, you can conduct a simple test on the lenses to verify their polarization.
The distinctive anti-glare technology embedded in these lenses, designed to shield your eyes from the sun, possesses characteristics that sharply contrast with those of non-polarized lenses.
To ascertain the polarization of your sunglasses, perform a test using a reflective surface, observe a computer screen, or carefully compare your pair with another. A convenient method is inspecting the ‘polarized markings’ usually along the temple. If uncertainty lingers, follow these steps: place the sunglasses in front of a light source, whether from a TV screen or ceiling lights. Orient them at a 90-degree angle, and you’ll observe a lightening of the lens tint. Shift them to a 180-degree position, and you’ll observe the lenses again darkening. This quick examination ensures you are receiving a product that aligns with polarized standards.
What Are Polarized Sunglasses?
Polarized sunglasses are a type of sunglasses that have a special filter added to the lenses that reduces glare. Glare is caused by sunlight reflecting off of horizontal surfaces, such as water, snow, or the hood of a car. This reflected light can be very bright and uncomfortable to look at, and it can also make it difficult to see clearly.
Polarized lenses work by filtering out this horizontal light. The filter is made up of a thin film of plastic that is aligned in a specific way. This film only allows light waves that are vibrating in a vertical direction to pass through. As a result, the horizontal light waves that cause glare are blocked.
The benefits of wearing polarized sunglasses include:
- Reduced glare
- Improved clarity and visibility
- Increased comfort for your eyes
- Enhanced color perception
Polarized sunglasses are a good choice for anyone who spends a lot of time outdoors, especially in bright or sunny conditions. They are also a good choice for drivers, as they can help to reduce glare from the road and other vehicles.
However, there are a few things to keep in mind when wearing polarized sunglasses. First, they can make it difficult to see certain types of electronic displays, such as LCD screens. This is because the filters in polarized lenses can block out some of the light that is emitted by these displays. Second, polarized sunglasses can be more expensive than non-polarized sunglasses.
Overall, polarized sunglasses are a great option for anyone who wants to improve their vision and comfort in bright conditions. If you spend a lot of time outdoors, or if you are bothered by glare, then polarized sunglasses are definitely worth considering.
3 Easy Ways To Test If Your Sunglasses Are Polarized
Beyond the aforementioned techniques, here are three additional uncomplicated ways to confirm the legitimacy of your polarized sunglasses. Fear not, as these steps require no specialized tools, ensuring an easy and effective assessment of the polarization filters.
Method 1 – Reflective Surface
In this method, polarized sunglasses are tested through a reflective surface. Begin by locating any reflective surfaces; a mirror is an ideal example. If a mirror is unavailable, opt for any reflective tabletop or flat surface.
To execute this test successfully, position yourself at least 2 to 3 feet away from the reflective surface. Create glare by using a flashlight directed at the mirror, observing the reflection bouncing off in the opposite direction. Adjust the angle of the light source until the glare aligns with your eye level or within reach.
Now, don your polarized sunglasses and hold them approximately 6 to 8 inches in front of your eyes. Adjust the distance based on the lens size. Gradually rotate the sunglasses upward until they reach a 60-degree angle, with one lens slightly higher than the other. Assess the level of glare; if it diminishes or disappears entirely, congratulations, your sunglasses are polarized. However, at a 90-degree angle, the polarized filters would be ineffective, as this position cancels the vertical sieve’s effectiveness against horizontal light rays.
Method 2 – Compare Two Pairs of TAC Sunglasses
For this test, acquire two pairs of polarized sunglasses. Hold both pairs at eye level in their standard 180-degree position, ensuring enough light for clear visibility and maintaining a 1 to 2-inch gap between the lenses to prevent scratches.
Simultaneously look through both pairs and rotate one pair to approximately 60 degrees. If the overlapping area on the lenses darkens, both pairs are polarized. If no differences or darker shades appear in the overlapped area, the sunglasses lack polarization.
Method 3 – Test Card
The third test involves looking at a specialized pattern through polarized sunglasses. Some optical stores provide a polarized sunglasses test card featuring scenery with a ‘secret’ image or a missing part.
The pattern employs special paint for the hidden image, reflecting so much light that it appears white or shiny to the naked eye. This part of the pattern only reflects polarized light, which is blocked by polarized sunglasses, revealing a dark background pattern and crisper images.
Are Polarized Sunglasses Beneficial for Your Eyes?
Polarized sunglasses prove advantageous for outdoor activities, enhancing vision in the presence of excessive glare or light. They are particularly useful for driving, although not recommended for airplane maneuvers due to the LCDs used by pilots, which already possess anti-glare features.
