Are Polarized Sunglasses Right For You?
Are polarized sunglasses better? For glare, yes. A polarized lens filters the harsh light that bounces off roads, water, snow and car hoods, so bright days feel calmer on your eyes. For UV protection, they are no different from any other pair, and around some screens they can get in the way.
What Are Polarized Sunglasses?
Polarized sunglasses are sunglasses with a special filter in the lens that reduces glare. When sunlight hits a smooth, flat surface like calm water or a car hood, it reflects at one angle, and when that reflection lands in your eyes it reads as glare. The American Academy of Ophthalmology describes the filter like a miniblind in front of a window: only light coming through the slats gets in, so polarized lenses block the horizontal light bouncing off water and shiny surfaces while vertical light passes through.
That is also the short answer to what polarized means in sunglasses. It describes how the lens treats light, not how dark it looks or how much it costs. You can browse the full range in Quay's polarized sunglasses collection, where polarized styles are marked right in the variant name.
What Are the Benefits of Polarized Sunglasses?
The benefits of polarized sunglasses all come back to one thing, reduced glare from reflected light:
• Less eye strain. With reflections filtered out, you squint less on bright days and outdoor activities feel easier.
• Visual clarity. The AAO notes that objects may appear sharper and details easier to see, although the view can also look slightly darker.
• Easier time near water. Polarized lenses reduce surface glare, which can make it easier to see into the water..
• More comfortable driving. They tame the bounce off asphalt and windshields, which is why they are a favorite behind the wheel.
The AAO says people who wear polarized sunglasses often feel less tired after hours in bright sun, and lists fishing, boating, the beach, golf and snowy environments among the best uses.
Polarized vs. UV Protection: Are They the Same Thing?
No, and this is the most common mix-up. Polarization controls glare. UV protection is a separate property of the lens, and the AAO is blunt that blocking UV does not mean a lens is polarized. A lens can have one without the other.
At Quay, every lens blocks 100% of UVA and UVB rays whether it is polarized or not, so the choice between the two comes down to glare, not protection. If you want the full breakdown of the rating, our UV400 sunglasses explainer walks through what to look for on a label.
Are Polarized Sunglasses Better in Every Situation?
No. Polarized lenses are a tool for specific situations, not an automatic upgrade, and the AAO lists a few times to skip them:
• Screens. They can make LCD screens hard to read, including car dashboard controls, ATMs, phones and some watches. Pilots, for example, are advised against them for this reason.
• Spotting ice. Polarized lenses can make icy patches harder to see while driving or skiing.
• Night driving. The AAO says they may do more harm than good.
If your day is mostly screens and short commutes, a pair of non-polarized sunglasses does the job. Our polarized vs. non-polarized comparison goes deeper on choosing between them.
Are Polarized Sunglasses Worth It?
Polarized sunglasses are worth it if your bright hours are spent near water, on the road or in the snow, or if glare tends to leave you squinting and tired. They are less of a priority if you mostly wear sunglasses for style on short walks. Many people keep one polarized pair for sunny drives and weekends, and non-polarized sunglasses for everything else. Either way, UV rays are handled by the lens rating, not by polarization.
If you are shopping, HIGH KEY and NIGHTFALL are two Quay bestsellers that come in polarized options.
How to Tell If Sunglasses Are Polarized
The quickest way to tell if sunglasses are polarized is to check the product page or label, since polarized lenses will say so. The AAO also advises checking the label rather than assuming that UV protection means polarization. For a pair already in your drawer, try the screen test: look at a phone or laptop screen through the lens and slowly rotate the glasses 90 degrees. If the screen darkens or blacks out, the lens is polarized. For more tests, see our guide to everything you have been wondering about polarized sunglasses.
Frequently Asked Questions
Are polarized sunglasses better than non-polarized?
They are better at reducing glare from reflective surfaces like water, roads and snow. They are not better at UV protection, and they can be worse around LCD screens.
Do polarized sunglasses protect your eyes from UV?
Not by themselves. Polarization and UV protection are separate. Check that the lens states its UV protection, and remember that every Quay lens blocks 100% of UVA and UVB rays.
Are polarized sunglasses good for driving?
Yes, in daylight; many people like them for daytime driving because they cut glare off the road. Be aware that they can dim dashboard screens, and the AAO advises against them for night driving.
What are the disadvantages of wearing polarized sunglasses?
The main drawbacks are trouble reading LCD screens, difficulty spotting ice, and a poor fit for night driving, according to the AAO. The lenses can also look slightly darker.
Who should not wear polarized sunglasses?
Anyone who needs to read LCD screens for navigation or work, such as pilots, and anyone who needs to spot ice on the road or slope.
