Sunglasses are no longer just a fashion statement—they are an essential accessory that protects your eyes from the sun’s harmful rays. But not all sunglasses are created equal. Polarized sunglasses offer superior protection by cutting glare and enhancing visual clarity. If you’ve purchased a pair and are wondering whether they’re actually polarized, you’re not alone.
At ROYALTAIL, we believe in transparency, quality, and education. That’s why we’ve created this complete guide to help you identify whether your sunglasses are truly polarized—so you can enjoy every sunny adventure with full confidence.
What Are Polarized Sunglasses?
Before diving into the tests, it’s important to understand what polarization is.
Polarized lenses are treated with a special chemical film that blocks horizontally reflected light—this is the kind of glare you get from water, roads, glass, snow, and other flat, shiny surfaces. This means:
-
Better clarity and contrast
-
Reduced eye strain
-
Enhanced comfort
-
Safer outdoor activities (especially driving or boating)
Why It Matters to Know If Your Sunglasses Are Polarized
Many sunglasses are simply tinted, not polarized. Tinted lenses reduce brightness but do not eliminate glare. That’s where polarization comes in. Glare can cause eye fatigue, poor visibility, and even dangerous driving conditions.
Key Benefits of Polarized Sunglasses:
✅ Glare reduction
✅ Better contrast and color perception
✅ Safer outdoor activity
✅ Comfort during extended wear
✅ UV protection (if included)
At ROYALTAIL, all of our polarized sunglasses offer full UV400 protection with premium anti-glare coating, combining safety and style in one elegant package.
How to Check if Your Sunglasses Are Polarized: 7 Easy Tests
1. Look for a Label or Marking
The simplest place to start is your sunglasses' packaging, label, or inside the temple arm. If the sunglasses are truly polarized, it often says:
-
"Polarized"
-
"P" next to the lens model code
-
“UV400 Polarized Protection” (especially on ROYALTAIL packaging)
However, be cautious—some low-quality brands may falsely label their sunglasses. That’s why it’s important to use the following practical tests.
2. Use a Digital Screen Test (LCD Test)
This is one of the most reliable home tests.
Steps:
-
Take your sunglasses and find an LCD screen (your smartphone, computer monitor, or ATM screen).
-
Hold the sunglasses in front of the screen and rotate them at a 60–90° angle.
-
If the lenses are polarized, you’ll notice the screen darken or even turn completely black as you turn the sunglasses.
Why it works:
Polarized lenses block specific light angles. LCD screens also emit polarized light. When they’re at opposing angles, the light cancels out, causing the blackout effect.
3. Try the “Double Pair” Test
If you already have a confirmed polarized pair of sunglasses (like your trusted ROYALTAIL pair), you can use it to test others.
Steps:
-
Hold the two pairs of sunglasses facing each other.
-
Look through both lenses.
-
Rotate one pair to a 90° angle.
If both are polarized, the overlapping area will darken significantly or go completely black.
4. Check for Glare Reduction Outdoors
Polarized sunglasses are noticeably different in bright conditions.
Try this:
-
Stand near a reflective surface—like a car windshield, a puddle, or the ocean.
-
Look at the glare with your sunglasses.
-
If the reflection fades or disappears, your sunglasses are likely polarized.
ROYALTAIL sunglasses make this easy: you’ll instantly see clearer textures, deeper colors, and zero white glare when viewing reflective surfaces.
5. Ask Your Optician or Use a Polarization Tester
Most opticians and eyewear stores have polarized light testers that clearly show how light is blocked. If you're unsure about your pair, a quick visit to a local eyewear shop can give you a definite answer.
At ROYALTAIL stores or authorized resellers, each polarized model is clearly marked and verified using industry-standard tools.
6. Online Product Page Verification
If you bought your sunglasses online, go back to the product page and check the specifications. Genuine brands like ROYALTAIL list polarization under:
-
“Lens Features”
-
“Sun Protection”
-
“Specifications”
Look for terms like:
-
“Polarized Lenses”
-
“Anti-Reflective Coating”
-
“Glare Reduction”
-
“UV400 Protection”
Avoid vague descriptions like “dark tinted lenses”—this doesn’t confirm polarization.
7. Price and Quality Test (Optional)
While not a foolproof test, price can be an indicator. Polarized lenses require extra processing and materials, so sunglasses below a certain price point (especially under ₹500) are less likely to offer real polarization.
ROYALTAIL’s polarized models start from affordable luxury pricing but always come with:
-
Lens certification
-
Packaging that mentions polarization
-
Lifetime UV protection assurance
Common Myths About Polarized Sunglasses
Let’s bust a few common misconceptions:
❌ Myth: “All dark lenses are polarized.”
Truth: Tint reduces brightness, but does not block glare. Only polarized lenses can do that.
❌ Myth: “You don’t need polarized lenses unless you’re on water.”
Truth: Glare is everywhere—on roads, glass buildings, and snow. Polarization helps anytime you're outdoors.
❌ Myth: “Polarized sunglasses are bad for screens.”
Truth: Polarized lenses may affect visibility on some LCD screens, but that’s due to their effectiveness at blocking specific light. ROYALTAIL lenses are balanced to reduce screen distortion while maximizing outdoor performance.
