Quick Answer

Choose polarized sunglasses if you mainly deal with strong reflected glare from water, wet roads, or other bright surfaces. Choose non-polarized sunglasses if you rely heavily on HUDs, digital dashboards, LCD screens, or prefer fewer display-visibility issues.

For eye protection, UV400 or 99–100% UVA/UVB protection matters more than polarization. The best lens depends on your activity, screen use, and glare exposure.

Polarized sunglasses are often marketed as the better choice because they reduce harsh glare from water, roads, snow, and other reflective surfaces.

But they are not automatically better for everyone.

In some cars, polarized lenses can make digital dashboards, LCD screens, or head-up displays (HUDs) look dim or harder to read. On the water, however, that same glare-reducing filter can make a big difference.

The real question is not polarized vs non-polarized: which is better? It is which one fits your daily use better?

One important thing to know first: polarization and UV protection are separate features. A non-polarized lens can still provide excellent eye protection if it is rated UV400 or blocks 99–100% of UVA and UVB rays.

In this guide, we’ll compare both lens types for driving, dashboards and HUDs, fishing, water sports, snow, aviation, screens, and everyday outdoor use so you can choose based on how you actually wear your sunglasses.

Key Takeaways

  1. Polarization reduces glare; UV protection protects your eyes.
  2. Non-polarized UV400 lenses can still provide full UV protection.
  3. Polarized lenses may make some dashboards, screens, and HUDs harder to see.
  4. Polarization is especially useful around water and strong reflected glare.
  5. Non-polarized lenses can be more practical for some screens, aviation, and display-heavy situations.
  6. Neither option is automatically better; the right choice depends on your activity.

Before comparing the trade-offs, let’s look at what a polarized lens actually does.

What Are Polarized Lenses and How Do They Work?

Reflected Glare
Bright light reflecting from water, roads, snow, or glass.
Polarized Filter
Reducing reflected horizontal glare
Less Reflected Glare
Less distracting glare reaches the eye for a more comfortable view.
Polarization reduces reflected glare. UV protection is a separate feature, so check for UV400 or 99–100% UVA/UVB protection too.

Polarized lenses use a special filter to reduce reflected glare from surfaces such as water, wet roads, snow, and glass.

Think of the filter like microscopic vertical blinds. Reflected glare is largely horizontally oriented, so the filter blocks much of it while allowing useful light to pass through. The result is less squinting and clearer vision in bright, reflective conditions.

This is why polarization is especially useful for driving, fishing, boating, and other activities around water.

Polarization Is Not UV Protection

Polarization and UV protection are separate features.

Polarization controls glare. UV protection helps shield your eyes from ultraviolet radiation. A non-polarized lens can still provide full UV protection if it is rated UV400 or 99–100% UVA/UVB protection.

When buying sunglasses, check for both:

  • UV400 or 99–100% UVA/UVB protection for UV safety
  • Polarization if glare reduction matters for your activities

So, what are you really paying for with polarized lenses? Better glare control and clearer vision in reflective environments.

What Non-Polarized Lenses Do

Non-polarized lenses reduce overall brightness without selectively filtering reflected glare.

So instead of specifically cutting glare from water, roads, snow, or glass, they simply make the entire scene darker.

How They Differ From Polarized Lenses

Polarized lenses target reflected glare. Non-polarized lenses do not.

That means some glare may remain visible, but the view can feel more natural and less altered.

Where Non-Polarized Lenses Can Be Useful

Non-polarized lenses can make sense when:

  1. You rely heavily on digital dashboards, LCD screens, or HUDs
  2. You prefer a more natural-looking view
  3. You mostly wear sunglasses for general everyday use
  4. Conditions are overcast or low-glare
  5. Strong reflected glare is not your main concern

They can also be a practical choice for display-heavy driving because they are less likely to interact with polarized screen output.

Non-polarized does not mean less UV protection. A properly rated non-polarized lens can still provide UV400 or 99–100% UVA/UVB protection.

Key Differences Between Polarized and Non-Polarized Lenses

The biggest difference is simple: non-polarized lenses reduce overall brightness, while polarized lenses also target reflected glare.

That difference affects glare control, screen visibility, color perception, price, and where each lens works best.

Attribute Polarized Lenses Non-Polarized Lenses
Glare Reduction Reduces reflected glare from water, roads, snow, and glass Reduces overall brightness but does not selectively filter reflected glare
Color & Contrast Can improve perceived contrast by reducing glare washout Often keeps a more natural-looking view
Screen Visibility May dim or interfere with some LCDs, dashboards, and HUDs Usually easier to use with screens and digital displays
UV Protection Not automatic; check for UV400 or 99–100% UVA/UVB Can provide full UV protection without polarization
Price Usually costs more Often more affordable
Best Use Cases Fishing, boating, bright-road driving, high-glare environments Everyday use, screen-heavy situations, lower-glare conditions
Low-Light Use Darker polarized tints may reduce too much light Available in lighter tints, but sunglasses are still not intended for night driving
Comfort in Glare Can reduce squinting caused by reflected glare Reduces brightness but leaves more reflected glare visible

The value of polarization becomes most noticeable in bright, reflective environments. If glare is not your main problem, the simpler non-polarized option may be more practical.

How this guide was researched: I compared manufacturer lens specifications, eye-health guidance, aviation guidance, product information, and recurring user feedback. I do not claim hands-on testing unless specifically stated.

Benefits of Polarized Sunglasses

Polarized lenses are most useful when reflected glare is the main problem. Unlike a regular tint, they selectively reduce glare bouncing off flat, reflective surfaces.

Better Glare Control

Water, wet roads, snow, and glass can create intense reflected glare. A regular tinted lens makes the whole scene darker, but much of that glare can still remain.

Polarized lenses reduce more of this reflected light, which can make details easier to see in bright conditions.

This is especially useful for:

  1. Driving on bright or wet roads
  2. Fishing and boating
  3. Beaches and open water
  4. Snowy or highly reflective environments

Expert Tip: Polarization can be very helpful for road and water glare, but check how the lenses interact with your dashboard, LCDs, or HUD before buying.

Improved Contrast in Bright Conditions

Strong glare can wash out detail and make a scene look flat. By reducing that glare, polarized lenses can improve perceived contrast and visual clarity.

Some premium lens technologies add extra color-enhancing treatments. For example, Maui Jim says its PolarizedPlus2 lenses eliminate 99.9% of glare while enhancing color, contrast, and depth perception. Maui Jim sunglasses are also recommended by the Skin Cancer Foundation as an effective UV filter for the eyes and surrounding skin.

Product Note: These color-enhancement benefits come from Maui Jim’s wider lens technology, not polarization alone.

Less Squinting and Better Visual Comfort

Bright reflected glare can make you squint and may contribute to visual fatigue during long periods outdoors.

I’m especially sensitive to bright summer glare because I experience migraines, so visual comfort matters a lot to me when choosing sunglasses. That personal experience is one reason I pay close attention to glare reduction, although migraine triggers and relief can vary from person to person.

By reducing that glare, polarized lenses can make driving, fishing, boating, and other bright outdoor activities more comfortable. They do not prevent every type of eye strain or headache, but they can reduce the discomfort caused specifically by reflected glare.

Polarization has limitations too, especially around certain screens and digital displays.

Situations Where Polarized Lenses Are Not Ideal

Polarized lenses are excellent for reflected glare, but they are not automatically better in every situation. Digital displays, aviation, some snow conditions, and low light all need extra consideration.

1. Digital Dashboards, Screens, and HUDs

This is one of the biggest reasons to check polarized sunglasses before using them for driving.

Polarization can interact with some LCD screens, digital dashboards, and head-up displays (HUDs). Depending on the display and viewing angle, information may look dim, distorted, or harder to read.

Tilting your head can also change visibility because the polarization angle changes relative to the screen.

Expert Tip: Test polarized sunglasses with your own dashboard and HUD before buying. Screen compatibility varies by vehicle.

Non-Polarized: HUD and digital display clearly visible
Polarized: HUD/display noticeably dimmer at a certain viewing angle

2. Pilots and Display-Heavy Work

The FAA does not recommend polarized sunglasses for aviation because they can interfere with some cockpit displays and create unwanted effects through laminated windscreens.

For pilots, neutral gray non-polarized lenses are generally the safer choice for maintaining natural color recognition and instrument visibility.

A similar consideration applies to jobs that rely heavily on LCD control panels or digital instruments.

Best approach: If reading a display is safety-critical, test the eyewear with the actual equipment rather than assuming polarization will work.

3. Skiing and Snowboarding

Snow creates strong glare, so polarization can certainly improve comfort on bright slopes.

But there is a trade-off.

Reflections can sometimes help reveal icy patches and changes in snow texture. Reducing those reflections may make certain terrain cues less obvious.

That does not mean polarized lenses are always wrong for skiing. Lens tint, contrast enhancement, VLT, weather, and terrain also matter.

Expert Tip: Choose snow lenses according to light conditions and terrain, not polarization alone.

4. Night and Low-Light Driving

Ordinary sunglasses should not be worn for normal night driving because dark lenses reduce the amount of light reaching your eyes.

This limitation is not specific to polarization. Dark non-polarized sunglasses can reduce visibility too.

For nighttime driving, use clear corrective lenses if needed, rather than ordinary tinted sunglasses.

Quick Guide

Situation Polarized? Why
Digital dashboard / HUD Check first Some displays may dim or become difficult to read
Aviation Usually avoid Can interfere with instruments and windshield visibility
Skiing / snowboarding Depends Reduces glare but may also reduce some reflective terrain cues
Night driving Avoid sunglasses Dark lenses reduce available light regardless of polarization

Polarization is useful when glare is the problem, but display visibility, terrain cues, and available light can matter more in these situations.

Next, let’s look at the feature that matters regardless of polarization: UV protection.

UV Protection Explained: Why It Is Separate From Polarization

This is the most important distinction in the whole guide: Polarization controls glare. UV protection protects your eyes from ultraviolet radiation.

They are separate features.

What UV400 Actually Means

Look for sunglasses labeled:

  1. UV400
  2. 99–100% UVA/UVB protection

UV400 generally means the lens is designed to block ultraviolet wavelengths up to about 400 nanometers, covering the UVA and UVB ranges.

A lens can be non-polarized and still provide excellent UV protection. Likewise, the word “polarized” alone does not tell you how much UV protection a lens provides.

Expert Tip: Always check the UV rating separately, even when the sunglasses are polarized.

Why UV Protection Matters

UV exposure can affect several parts of the eye.

Intense short-term exposure can cause photokeratitis, sometimes called snow blindness. Long-term UV exposure is associated with eye conditions including cataracts and other UV-related damage. The CDC specifically recommends sunglasses that block 99–100% of UVA and UVB radiation.

UV exposure can be especially intense around highly reflective environments such as snow and water, where reflected radiation can increase exposure.

If You Must Prioritize One Feature

If your budget is limited, prioritize proper UV protection before polarization.

A non-polarized pair with verified UV400 or 99–100% UVA/UVB protection can still provide the UV protection your eyes need.

Polarization is mainly about glare control and visual comfort. UV protection is the feature directly related to reducing UV exposure.

Frame Coverage Matters Too

Lens protection is only part of the equation.

Larger and wraparound frames can reduce UV entering from the sides, which is why the CDC recommends wraparound sunglasses for better coverage.

Lens Darkness Does Not Equal UV Protection

A darker lens is not automatically safer.

Tint darkness mainly changes how much visible light reaches your eyes. UV protection depends on the lens’s UV-blocking properties, not simply how dark the lens looks.

So a lighter lens with proper UV protection can be safer than a very dark lens without verified UV blocking.

Lens color mainly changes how the world looks through the lens. For example:

  1. Gray: keeps colors relatively neutral
  2. Yellow/amber: can increase perceived contrast in some conditions
  3. Neither color automatically adds UV protection

Expert Tip: Check the UV rating first. Tint color and polarization are secondary features.

Next, let’s look at a quick way to tell whether a pair of sunglasses is actually polarized.

How to Tell If Sunglasses Are Polarized

A dark tint does not prove that sunglasses are polarized. Polarization is easiest to check by comparing the lens with another polarized source.

Here are three simple tests.

Test 1: Use an LCD Screen

Hold one lens in front of an LCD screen and slowly rotate the sunglasses about 60–90 degrees.

If the screen becomes noticeably darker at certain angles, the lens is likely polarized.

This happens because the sunglass filter interacts with polarized light coming from the display.

Important: Not every modern phone or display behaves the same way, so a screen that does not darken is not always definitive proof that the sunglasses are non-polarized.

Test 2: Check Reflected Glare

Look through the sunglasses at glare reflecting from a flat surface such as water, glass, or a car hood.

Slowly tilt the sunglasses or your head. With polarized lenses, the intensity of the reflected glare should change as the lens orientation changes.

This is a useful real-world check, although lighting and viewing angle can affect the result.

Test 3: Use Another Polarized Lens

This is the clearest home test.

Place the sunglasses in front of a pair you already know is polarized and look through the overlapping lenses. Slowly rotate one pair about 90 degrees.

If both lenses are polarized, the overlapping area should become much darker, often nearly black, when the filters are crossed.

This is known as the crossed-polarizers effect.

Expert Tip: If you want the most reliable quick check, compare the sunglasses with another known polarized lens.

What the Test Does Not Tell You

These tests only check polarization.

They do not confirm UV protection. A lens can:

  1. Be polarized without telling you its UV rating
  2. Be non-polarized and still provide UV400 protection

So always check polarization and UV protection separately.

Which Lens Type Is Right for You?

The best choice depends on how you actually use your sunglasses.

Polarized lenses make the most sense when reflected glare is your main problem. Non-polarized lenses can be more practical when screens, displays, low-glare conditions, or specific visual cues matter more.

Whichever lens you choose: look for UV400 or 99–100% UVA/UVB protection. Polarization and UV protection are separate features.

Drivers: Check the Dashboard First

Polarized lenses can be excellent for driving because they reduce glare from wet roads, pavement, glass, and other vehicles.

The trade-off is screen compatibility. Some digital dashboards, LCDs, and head-up displays can look dimmer or harder to read through polarized lenses, especially at certain viewing angles. That is why it is worth checking the lenses against your own dashboard and HUD before buying.

This is also one of the trade-offs I cover in my Oakley Prizm Sapphire Polarized review, especially for drivers who use digital displays.

If your display becomes difficult to read, a non-polarized UV400 lens may be the more practical choice. It will still reduce overall brightness, just without the same level of reflected-glare control.

Boaters and Anglers

This is one of the strongest use cases for polarization.

Water creates intense reflected glare, and polarized lenses can make it easier to see below the surface, which is useful for spotting fish, structure, depth changes, and submerged objects.

If water use is your main priority, my Costa 580G Blue Mirror review looks at a lens designed specifically for strong fishing and boating glare.

Maui Jim says its PolarizedPlus2 technology eliminates 99.9% of glare while enhancing color and contrast, which is why this type of lens technology is especially popular for fishing and boating.

Skiers and Snowboarders

Polarization can reduce harsh snow glare, but there is a trade-off.

Reflections can sometimes help reveal icy patches and changes in snow texture. Reducing those reflections may make certain terrain cues less obvious.

Some skiers prefer non-polarized, contrast-enhancing, or photochromic lenses, especially in changing light. My guide to the best rose-tinted sunglass lenses includes options designed to improve contrast in snow and changing light. For snow sports, it makes more sense to consider terrain, VLT, contrast, and weather rather than choosing based on polarization alone.

Pilots and Display-Heavy Work

The FAA generally advises against polarized sunglasses for pilots because they can interfere with some cockpit displays and create unwanted effects through aircraft windscreens.

Neutral gray non-polarized lenses are commonly recommended for flying.

A similar consideration applies to jobs that depend heavily on LCD instruments or control panels. In those cases, screen readability should come before glare reduction.

Everyday and Budget-Conscious Shoppers

For general outdoor use, either lens type can work well.

Polarized lenses offer extra comfort when reflected glare is common, but a non-polarized UV400 pair can still provide proper UV protection at a lower price.

If budget is limited, prioritize UV400 or 99–100% UVA/UVB protection first, then fit and coverage, and only pay extra for polarization if glare reduction actually matters for your routine.

If your week includes both glare-heavy activities and lots of screen use, owning one polarized and one non-polarized pair can be a practical solution.

Next, let’s compare real products across different price ranges.

Real-World Product Comparison: Budget to Premium

Polarization is available at almost every price level, so cost alone does not decide which lens type is better.

Here are a few examples of how budget, everyday, and premium options differ.

1. Budget Polarized: Knockaround Premiums

Knockaround Premiums

View at Knockaround

Knockaround Premiums are one of the more affordable polarized options. The standard polarized versions are typically around $35–$38, depending on colorway, and include 100% UVA/UVB protection. Some variants are also available with non-polarized color-enhancing lenses.

They make sense for buyers who want basic glare reduction without moving into premium pricing.

Check Current Price

2. Affordable Sport: Tifosi Swank

Untitled design 19 e1790525760106

Tifosi Swank

The Tifosi Swank line sits above entry-level sunglasses and is aimed at active everyday use.

Polarized versions are useful for runners, casual cyclists, and outdoor users who want glare reduction in a lightweight frame. If fit is a concern, the Swank XL is designed for larger faces.

The main reason to move up from a basic budget pair is usually frame fit, lens options, and sport-oriented design, not UV protection alone.

Check Current Price

3. Everyday Non-Polarized: Ray-Ban Erika

Untitled design 21 e1790525812256

The Ray-Ban Erika is a good example of a lifestyle frame that is available with traditional tinted lens options rather than being built purely around polarization.

A non-polarized configuration can suit buyers who prioritize everyday city wear, natural-looking color, and easier compatibility with screens.

Pricing varies by lens and retailer, so it is better to check the exact configuration rather than treat one price as standard.

Check Current Price

4. Premium Sport: Smith Wildcat ChromaPop

The Smith Wildcat is currently listed at $217 on Smith’s official site. It combines large coverage with ChromaPop lens technology, which Smith says improves color separation, definition, and clarity.

The Wildcat is more about coverage, sport fit, airflow, and contrast-enhancing lens technology than simply choosing polarized versus non-polarized.

That makes it a better fit for cyclists, runners, and trail users who care about performance-oriented coverage.

Oakley offers polarized versions across many sport and lifestyle models, often combining Plutonite lens material with lightweight O Matter frames.

Some models, such as certain Drop Point configurations, meet ANSI Z87.1 optical and impact standards, while Oakley also states that Plutonite lenses filter UVA, UVB, and UVC up to 400 nm.

Because certifications vary by model, check the exact product specifications if impact protection is important to you.

If you are comparing Oakley lens options rather than just frames, see my Oakley Prizm Lens Guide for VLT, base tint, polarization, and activity differences.

6. Premium Polarized Water and Everyday Use: Maui Jim

Untitled design 23 1 e1790526234744

Maui Jim

View at Amazon

Maui Jim is one of the strongest premium examples of polarization-focused lens technology.

The company states that its PolarizedPlus2 lenses eliminate 99.9% of glare and provide 100% UV protection. Maui Jim sunglasses also carry the Skin Cancer Foundation Seal of Recommendation as an effective UV filter for the eyes and surrounding skin.

That makes them especially relevant for water, boating, fishing, and other high-glare environments.

However, premium polarization does not remove the screen-compatibility issue discussed earlier. If you rely on a dashboard or HUD, compatibility still matters regardless of price.

Check Current Price

What Price Actually Changes

Paying more can improve things like:

  1. Lens clarity and optical design
  2. Frame construction and fit
  3. Impact resistance
  4. Coatings
  5. Contrast-enhancing technology
  6. Coverage and comfort

But UV protection does not have to be expensive, and polarization is still an optional feature based on use.

The best value is not automatically the most expensive pair. It is the one that combines verified UV protection, the right lens type, comfortable fit, and features that match your activity.

Eye Health Considerations: What the Science Says

Polarization mainly affects glare and visual comfort. For eye health, the more important feature is proper UV protection.

Short-Term UV Damage: Photokeratitis

Photokeratitis is a painful, temporary injury caused by intense UV exposure to the eye. It is often compared with a sunburn of the cornea and conjunctiva.

Common symptoms include:

  1. Eye pain
  2. Redness
  3. Tearing
  4. Light sensitivity
  5. Blurred vision

Snow blindness is a form of photokeratitis caused by UV reflected from snow and ice. Water and other reflective surfaces can also increase UV exposure.

Long-Term UV Exposure

UV exposure also adds up over time.

Long-term exposure is associated with a higher risk of several eye conditions, including cataracts and other UV-related damage. The American Academy of Ophthalmology recommends sunglasses that block at least 99% of UV light as part of cataract prevention.

Why UV400 Matters More Than Polarization

Look for sunglasses labeled:

  1. UV400
  2. 100% UV protection
  3. 99–100% UVA/UVB protection

UV400 generally means the lenses are designed to block ultraviolet wavelengths up to about 400 nanometers.

Polarization does something different. It reduces reflected glare from surfaces such as water and roads, but polarization alone does not guarantee UV protection.

What to Check Before Buying

Do not judge UV protection by:

  1. Price
  2. Lens darkness
  3. Lens color
  4. Polarization alone

Instead, check the manufacturer or product label for verified UV protection.

A less expensive pair with proper UV400 protection can protect against UV just as effectively as a premium pair if both meet the same UV standard. Cleveland Clinic likewise recommends putting full UV protection ahead of price or polarization.

The takeaway is simple: choose UV protection for eye safety, then choose polarization based on glare and how you use your sunglasses.

Next, here is how this guide was researched and evaluated.

Trust, Transparency, and Methodology

This guide is based on four main factors: UV protection, lens type, price range, and real-world use-case fit.

UV protection comes first. I prioritize lenses labeled UV400 or 99–100% UVA/UVB protection, then look at whether polarization actually adds value for the activity.

Product details such as lens material, polarization, frame features, dimensions, and pricing are checked against manufacturer specifications and reputable retailer listings. Eye-health information is based on guidance from sources such as Cleveland Clinic and the American Academy of Ophthalmology.

The recommendations also consider how each lens type is likely to perform in common situations, including:

  1. Driving and dashboard visibility
  2. Fishing and water glare
  3. Snow and changing terrain
  4. LCD screens and digital instruments
  5. Everyday outdoor use
  6. Budget and ownership trade-offs

No product is presented as personally tested unless that testing has actually taken place. Where a claim comes from a manufacturer, it is treated as a manufacturer claim rather than independent testing.

Quick Reference: Your Lens Type Cheat Sheet

Choose Polarized Lenses If:

  1. You spend a lot of time fishing, boating, or around water
  2. Reflected glare from roads, water, snow, or glass is your main problem
  3. You want better glare comfort during long, bright outdoor days
  4. Your car’s dashboard and HUD remain easy to read through them

Choose Non-Polarized Lenses If:

  1. Polarized lenses make your HUD, dashboard, or LCD screens harder to see
  2. You fly or regularly depend on digital instruments
  3. You work outdoors with screens
  4. You prefer a more natural-looking view
  5. Preserving reflective terrain cues matters for your snow activity

Either Can Work If:

  1. You mainly want everyday sunglasses
  2. Strong reflected glare is not a major issue
  3. The lenses provide UV400 or 99–100% UVA/UVB protection

Avoid These Mistakes:

  1. Wearing dark sunglasses at night or in low light
  2. Assuming polarization automatically means UV protection
  3. Assuming darker lenses provide stronger UV protection
  4. Choosing polarization without checking important screens first

Final Verdict: It Depends on What You Do

There is no universal winner.

Choose polarized lenses if reflected glare from water, roads, or other bright surfaces is your main problem.

Choose non-polarized lenses if screen visibility, HUDs, digital instruments, or certain visual cues matter more.

For skiing, the better choice depends on light conditions, terrain, VLT, and lens technology.

Whichever lens you choose, prioritize UV400 or 99–100% UVA/UVB protection first.

If you use a digital dashboard or HUD, check the sunglasses with your own display before buying. And if your routine includes both glare-heavy activities and lots of screen use, owning one pair of each can be the most practical option.

The best lens is simply the one that matches how and where you actually use it.

Frequently Asked Questions

Do polarized sunglasses protect against UV rays?

Not automatically. Polarization reduces reflected glare, while UV protection is a separate feature. Look for UV400 or 99–100% UVA/UVB protection on the label.

Will polarized lenses make my car's dashboard or HUD unreadable?

They can. Some LCD dashboards and head-up displays may look dim, distorted, or harder to read through polarized lenses, especially at certain viewing angles. Test them with your own vehicle before buying.

Are non-polarized sunglasses less safe for my eyes?

No. Non-polarized sunglasses can still provide full UV protection if they are rated UV400 or 99–100% UVA/UVB protection.

Which lens is better for fishing or boating?

Polarized lenses are usually the better choice because they reduce glare from the water and can make it easier to see below the surface.

Can I wear polarized sunglasses at night?

Ordinary tinted sunglasses, whether polarized or not, are not suitable for normal night driving because they reduce the amount of light reaching your eyes.

How can I tell if sunglasses are polarized?

Hold one lens in front of an LCD screen and slowly rotate it about 60–90 degrees. If the screen becomes noticeably darker, the lens is likely polarized.

For a more reliable check, compare it with another pair you already know is polarized. When the two filters are crossed at about 90 degrees, the overlapping area should become much darker.
