Sunglasses are great — whether you’re choosing stylish women’s sunglasses or rugged men’s sunglasses. But if you really want the best eye protection, you need polarized lenses. How do you know your sunglasses are polarized? The good news is that it’s pretty simple. You don’t need special tools or a science degree. You can check them at home, and we’ll show you how. Let’s get started!
Easiest Way: Use Your Computer Screen
One of the fastest ways to check is to look at your computer screen. It works better than your cell phone, so bring your laptop or desktop computer if you can.
The method is as follows:
- Put your sunglasses in front of your eyes.
- Look at the screen through the lenses.
- Rotate your sunglasses 90 degrees.
What happens: If the lenses are polarized, you will notice that the screen darkens. If there is no change, the lenses are not polarized.
Tip: Make sure the screen brightness is turned up. This makes the effect easier to spot.
FAQ: Does it matter what kind of computer I use?
- No! Any LCD screen will work fine.
Outdoor Test: Sunlight and Asphalt
No computer? No problem. Nature has your back.
Try this:
- Go outside on a sunny day.
- Look at something flat and reflective, like asphalt, water, or a windshield.
- Rotate your sunglasses 90 degrees while looking through them.
What to Expect: If they are polarized, the glare changes. As you rotate your glasses, the surface may look darker or brighter.
Fun Fact: Polarized lenses block horizontal light waves, which is why they eliminate blinding glare.
Ask the Store (But It’s More Fun to Do It Yourself!)
Of course, you can always call or go to the place where you bought your sunglasses. They should know if the lenses are polarized or not.
However… Where’s the adventure in that? It only takes a minute to test them yourself. Plus, you’ll learn something new and cool!
Tip: Some brands even have the word “polarized” on the inner arm of the sunglasses. Check first for a quick answer!
