Polarized sunglasses filter out glare caused by the suns rays meeting a horizontal surface such as a road, body of water, buildings, and much more. A built-in horizontal element fights this glare to allow pure light through, increasing contrast, clarity, & boosting color significantly.
What Are Polarized Sunglasses?
Polarized sunglasses look like any other pair of sunglasses from the outside. It’s when you put them on that you immediately see what they are all about. Understanding what makes these lenses so special will have you ditching your conventional sunglasses in no time!
When the sun emits vertical rays, they eventually become absorbed, refracted, or reflected upon entering the earth’s atmosphere. All of this sunlight remains scattered until it reaches a flat or horizontal surface. Upon collecting on these flat surfaces, the sun’s rays become directionally concentrated or polarized, typically resulting in severe glare and bright reflections.
To combat this, polarized sunglasses feature a lens with a special film that blocks reflected horizontal light, leaving only vertical light to pass through to your eyes. This verticals light brings with it the clarity and contrast of your surroundings, resulting in exceptionally clear vision and pure color.
True visual color profiles, reduced color distortion.
Unique performance characteristics in certain instances like fishing.
Polarization is usually built into the lens as opposed to being just a coating on the lens.
Cons
Almost always adds an additional cost to a pair of sunglasses.
Can’t read most LCD or LED screens while wearing.
Some specific instances in sports where polarization can be a detriment.
Advantages of Polarized Sunglasses
While the glare blocking properties of polarized lenses are their greatest feature, they also possess other qualities that significantly enhance their worth. When wearing them, you will immediately notice your vision becomes sharper and the colors purer. Simply put, the sky will appear bluer, the grass greener, and water clearer all whileblocking the reflections typically emitted from these surfaces.
In fact, wearing polarized sunglasses while on the waterwhile boating or fishing is one of the truly spectacular visuals youneed to see tobelieve. The glare blocking properties will cut through all the polarized (concentrated) sunlight reflecting off the surface of the water, allowing you to see well below the surface. If youare on a clearer body of water, it is not uncommon to be able to see fish and other sea life well below the water‘s surface. This is simply impossible with non-polarized lenses as they can’t filter out glare and reflections, only block some of it.
Last, blocking glare and reflections will provide your eyes with a much-needed break from any potential eyestrain. Even with regular sunglasses, you may find yourself squinting in situations where there is excessive glare. If you are subjected to this for an extended period of time you will likely experience eyestrain and headaches.
Disadvantages of Polarized Sunglasses
Cutting right to the chase, one obvious issue with polarized lenses is the additional cost. To many people, this fact doesn’t, or won’t, matter given the added benefits already explained above. For the cost conscientious, this might make it a little harder to pull the trigger on polarized lenses. Though, there are quite a few options these days for affordable polarized sunglasses.
Aside from cost, there are also a few performance quirks in specific cases. If you have never owned a pair of polarized sunglasses, you will quickly learn they don’t mix well with LCD or LED screens. It can be difficult or near impossible to view the screens on frequently used items like smartphones, computers, and tablets.
Other instances of this phenomenon which may not be as obvious are screens on ATM machines, gas pumps and probably most importantly, your car’s instrument panels. Navigation screens, digital dashes, and heads-up displays will also likely disappear when wearing polarized lenses. This could be just an annoyance or downright dangerous depending on what car you drive.
Despite what you may have read elsewhere, the polarization of sunglass lenses is not the most critical factor when considering your next eyewear purchase. UV protection, as discussed above, is much more important for your eye health. The radiation in UVA and UVB rays can cause severe eye issues over time, so ensuring your sunglasses have adequate protection is a must. Sunglasses without UV protection are far more harmful to your eyes than clear lenses with proper UV protection.
Sunglasses block light waves to your eyes causing them to dilate, potentially letting more UV rays through. If your lenses don’t have the correct UV protection, you are essentially opening up your eye to a significant increase of UVA and UVB rays. That said, non-polarized sunglasses, and even 100% clear lens glasses with UV protective coatings, can block just as many UV rays as polarized sunglasses. You just won’t get to experience the dramatic reduction of glare and increased visual clarity without polarized lenses.
Mirrored lenses (also called flash coated) have become a hugely popular trend with sunglasses today. They offer great style with a myriad of color choices for the consumer. Although it was once somewhat rare to find a lens that was both mirrored and polarized, this is simply not the case anymore. Most eyewear companies now offered polarized mirrored lenses in dozens of colors. If this is your style, you will have plenty of options from which to choose. Again, double check the UV protection rating on any sunglasses you are thinking of purchasing to ensure adequate protection from both UVA and UVB rays.
Without a doubt, the most crucial aspect of sunglasses is their UV (ultraviolet) ray protection. There are UVA, UVB, and UVC rays and it’s essential that your sunglasses can handle all of them to protect your eyes. UVA rays can penetrate your eyes if left unprotected, causing eye issues like cataracts or macular degeneration. UVB rays are those which cause sunburns and can damage the delicate skin around your eyes. UVC rays are burnt off in the earth’s atmosphere, but many manufacturers like to market protection against them.
Thankfully any decent pair of sunglasses including polarized sunglasses can block or absorb 99% to 100% of all three UV ray types. UV protection of 99% to 100% is referred to as UV400 protection in the eyewear industry and should be at the top of your must-have features next time you are shopping for sunglasses. Most polarized sunglasses, especially from designer brands, will have a UV400 protection rating or something very close to it.
Are Polarized Sunglasses Right For You?
While we here at Eyewear Genius almost always go for polarized lenses we understand they may not be the best lens for everyone or every situation. We highly recommend you, at the very least, try a pair of polarized lenses for a few days to understand all the advantages and disadvantages outlined above. Once you do, we think you’ll agree with us that once you go polarized you never go back!
If you are having a hard time deciding on your next pair of sunglasses, browse our curated collections of both polarized and non-polarized sunglasses. We hand pick all the eyewear displayed on this site with strict parameters based on quality, key features, uniqueness, reputation, and much more.
Polarized Sunglasses FAQ
Do discount polarized sunglasses offer good UV protection?
Exercising caution when browsing generic or cheap sunglasses is also recommended when it comes to UV protection. More inexpensive sunglasses that merely have a sticker on the lens that states “UV protection” don’t always measure up to industry standards. However, this doesn’t mean that generic or cheaper sunglasses can’t achieve a true UV400 protection level. However, there is a far greater likelihood of UV protection discrepancies when dealing with cheap sunglasses and off brands.
Designer brands typically invest large sums of money to ensure that all of their lenses meet industry standards for polarization and UV protection. I am willing to bet that many cheap sunglass manufactures can’t, or won’t, verify their UV protection ratings or their polarization quality. The phrase “You get what you pay for” has never rung truer. If you are skeptical, you can have your local optometrist or optician test the UV protection of your current sunglasses. Additionally, you can test your sunglasses UV protection yourself following our UV protection testing guide.
It’s important to note that UV protection also doesn’t equate to optical lens quality. Many discount brands forego lens quality while offering UV protection. Designer brands, or more expensive sunglasses, almost always have incredibly high-quality lenses which have been lab tested to be optically clear. Even if you don’t notice the impurities, your eyes no doubt will. Lenses with small air bubbles or distortion can cause headaches, eye strain, and even nausea.
Are polarized sunglasses good for sports?
As I mentioned above, a couple of the best features of polarized lenses are glare reduction, increased clarity, and contrast- all of which are big pluses in the world of sports. Water sports like fishing, boating, and sailing benefit significantly from polarized lenses by substantially reducing water surface glare. They can even allow fishermen and women to see their lures as well as fish under the water’s surface, which I can tell you first hand is pretty awesome. Cyclists can enjoy reduced road glare allowing them to see oncoming traffic or hazards easily. Polarized lenses can also help to track a ball in the air while golfing or minimize glare while skiing, but there are specific negative instances relating to these examples that require more explanation.
Skiing & Snowboarding
Wearing polarized sunglasses or goggles while skiing can significantly reduce glare and reflection coming off of the stark white snow, providing improved sight and increased eye comfort. That said, polarized lenses will also eliminate the glare from any patches of ice on the slopes making it hard for skiers to see surface changes, especially when skiing aggressively.
Experienced skiers refer to this as “flat light,” and it can prove to be quite dangerous at times. Be sure to test your lenses before attacking the moguls or terrain park too aggressively.
While golfing with polarized lenses, your contrast will be significantly improved making it easier to track and find your golf ball. That being said, if you are on or near the green, they can hurt your short game. Many golfers rely on the reflection of the grass or grain to read their chips and putts.
With the glare and reflections eliminated, they may make the surface appear flat and make it nearly impossible to read the breaks. I recently hit the links and found I had to remove my sunglasses while putting, as trying to read the greens with them was just too difficult.
Cycling & Motorsport
Polarized lenses can be quite useful in fighting road glare and reflections from oncoming traffic as mentioned before. Nevertheless, they can pose a risk if worn on a race track or Tarmac rally stages. Many car or motorcycle enthusiasts enjoy track days, but wearing polarized sunglasses could put you into the wall.
Along with reducing the road surface glare, they will also eliminate the glare from any oil spots or water on the track. As any experienced track goer knows, one small oil slick can ruin your weekend and your car or bike. Much of this is also directly relatable to serious road cyclists as well.
Can children wear polarized sunglasses?
Parents, this one is simple. Yes, your kids can wear polarized sunglasses and should wear UV protective sunglasses at the very least. As we age, our eyes build up resistance to ultraviolet radiation (UVR) to only allow 2-3% through to the back of our eyes.
As children, we have not yet built up this resistance and about 20% of UVR can make its way to the back of the eye. That’s a staggering 1000% difference between a child’s eye versus that of a young adult. Just make sure your kids’ sunglasses have the following features, and your youngsters’ eyes will be sufficiently protected:
99-100% UVA and UVB protection.
Impact resistant CR39 or polycarbonate lenses for added safety.
A proper fitting, lightweight frame.
Does lens color matter?
In most instances, the color of the lens will have little to no adverse effects for the wearer. Certain lenses can offer things like darker tint or condition-specific lenses, but most can be chosen for their desired look or finish. That said, many polarized lenses are Amber, or gray because these two colors distort color the least. If you are participating in activities where pure color is important, I recommend you stick with lenses in those color families.
Are polarized lenses difficult to clean?
While not more challenging to clean than any other lens, polarized lenses typically have special coatings which require additional care. There are many articles available that specify how to clean eyewear with everything from rubbing alcohol to cleaning products like Windex. Let this be a warning right now; you will likely destroy your lenses if you clean them with anything other than soap and water. One other exception would be pH neutral eyewear cleaner specifically designed for your lens.
The polarization of the lens will likely remain intact when using household cleaners, but you will probably ruin any extra lens coatings like anti-glare, anti-scratch or most importantly, your lenses protective UV coating. You will also want to be sure to use a nice microfiber cleaning cloth or soft lint-free towel when drying your glasses. The use of things such as your t-shirt, paper towels, or anything with an abrasive surface could also remove protective lens coatings over time.
Are polarized sunglasses worth It?
The decision to purchase polarized sunglasses will ultimately come down to you weighing the pros and cons discussed above. We are strongly in favor of polarized sunglasses especially when paired with proper UV protection. I wear polarized sunglasses every day and enjoy the increased clarity and contrast in addition to the glare reduction.
I know I won’t be playing on the PGA tour or driving a Formula One car anytime soon, so I am not too concerned with the different issues that pop up during those activities. But that’s just me, and you will need to decide for yourself if the many benefits outweigh the added cost associated with polarized lenses.
