Finding a great pair of sunglasses is a lot of fun. But sometimes it’s hard to know exactly what kind of lenses you actually have. Maybe the label fell off, or you’re questioning whether you got what you paid for.
You can easily test if your sunglasses are polarized by holding them up to your phone screen and rotating them 90 degrees or by trying professional verification methods. Each approach takes just a few minutes and gives you clear answers about your eyewear.
Simple Phone Test for Polarized Lenses
Your smartphone provides the easiest way to check polarization at home. Open any app with a bright white background and hold your phone at arm’s length.
Put on your sunglasses and slowly rotate them 90 degrees while looking at the screen. If your glasses are polarized, the screen can darken dramatically or even appear completely black when rotated. Non-polarized sunglasses won’t create this effect. The screen stays the same brightness no matter how you turn your head.
This test works because phone screens emit polarized light. When your polarized lenses align perpendicular to the screen’s light waves, they block most of the light from reaching your eyes.
Visual Signs Your Glasses Are Polarized
Pay attention to how your glasses affect digital displays throughout your day. Car dashboard screens often become harder to read, especially when you tilt your head. ATM screens might look dimmed or completely black from certain angles.
These changes happen because, just like your phone screen, LCD technology uses polarized light. Your polarized lenses can block this light depending on how the screen is oriented compared to your glasses.
You don’t need technology to know if your lenses are polarized; you could just step outside. Polarized lenses dramatically reduce glare from reflective surfaces. You’ll see less harsh light bouncing off water, wet pavement, or car hoods on sunny days.
When driving, you can look through other car windshields more clearly without the blinding reflection. Snow and sand also become more comfortable to look at because the intense reflected light gets filtered out.
Professional Methods to Check Polarization
Optical shops often have polarized test filters you can use for comparison. However, you can do your own version of this test if you have a second pair of sunglasses you know for sure are polarized. With these frames, you can perform a cross-test.
Hold one pair in front of the other and rotate one 90 degrees. Polarized lenses can create a dark or completely black view when crossed this way.
If it’s still unclear what kind of coating your lenses have, your optometrist can also use specialized equipment to verify polarization. This option works well if you’re visiting for comprehensive eye care and want to confirm your sunglasses meet your needs.
Enjoy the Benefits of Polarization
Polarized lenses can reduce eye strain by cutting out harsh reflections. You may experience less squinting and fatigue during bright, sunny days. Plus, wearing these lenses can improve your color contrast. Blues appear deeper, greens look more vibrant, and you can distinguish details more easily in bright conditions.
Grab your polarized options for these specific activities:
- Fishing and boating
- Enjoying beach days
- Taking long drives in sunny weather
- Playing outdoor sports like golf, tennis, and cycling
When Polarized Glasses May Not Work Well
There are times when it’s better to opt for non-polarized lenses.
Polarized lenses can make icy surfaces harder to see while skiing or driving in winter. The polarization removes reflections that help you spot dangerous ice patches or changes in snow conditions.
You might struggle to read your phone or dashboard displays while driving. Some pilots avoid polarized glasses because aircraft instruments can become difficult to read at certain angles.
If your daily activities involve frequent screen reading or you need to see reflective surfaces for safety, non-polarized sunglasses might work better for your lifestyle. People who spend significant time on digital devices may also experience computer vision syndrome when polarized lenses interfere with screen visibility.
