As we all know, polarized sunglasses have many advantages. They can protect your eyes from glare, and help your eyes stay health. However, polarized sunglasses also have some drawbacks. If you want know more about polarized sunglasses, this is the article you should read.
What are Polarized Sunglasses?
Polarized sunglasses are a special type of eyewear that helps to reduce glare from sunlight. Glare is caused by light reflecting off of surfaces such as water or pavement. When this light enters the eye, it can cause discomfort and even temporary blindness. Polarized lenses work by absorbing horizontal light waves, which eliminates glare and makes it easier to see. In addition to reducing glare, polarized lenses also provide 100% protection from harmful UV rays.
While polarized sunglasses are great for reducing glare, they can also interfere with your ability to see fine detail. This is because polarized lenses block out light that is coming from all directions, including light that is reflected off of surfaces. As a result, polarized sunglasses can make it difficult to see things like small prints or intricate designs. If you need to see fine detail, it is best to remove your polarized sunglasses.

What are the Disadvantages of Polarized Sunglasses?
1-They Can Change How You See
Polarized Sunglasses offer protection from the sun’s harmful rays. But the downside to these types is you may not see properly when wearing them because your eyesight could come into conflict with what's in front or behind where one looks through the lens at an object off-screen (i e., near misses).
2- Lack of UV protection
Polarized lenses don’t block UVA or UVB rays. Some polarized lenses also offer UVA and UVB protection, but not all. People in areas with high levels of sunlight exposure may need pay attention to this problem.
3-Make it difficult to see LCD screens
LCD displays, which can be found in a cockpit, emit polarized light. Therefore, polarized sunglasses reduce the ability to read those LCD displays. A pilot with polarized sunglasses on could fail to see a shimmer of glare given off by another aircraft’s windscreen. This may also be an issue in some sports where watching the score or stats on large LCD screens is vital.
The protective effect of these sunglasses is usually achieved by adding a layer of COATING on the surface of the lenses. And this layer of coating may gradually be worn out under the influence of time and lose its function.
It is no wonder that polarized sunglasses cost more than regular ones. Although polarized sunglasses have many outstanding advantages, but for the buyers who only want to play the role of outdoor protection, the high price may seem very unreasonable. And with a little carelessness, if the purchase does not suit their style, such a large amount of money will indeed be very heartbreaking.
6- Comfort Issues
These lenses do not filter the light completely, which results in the penetration of harmful sunlight through the lenses. The constant disruption of light caused by the polarized lens can also cause a strain on the eyes when using tech devices. The coating of the polarized lenses makes it difficult, and induces a strain on the nerves of the eyes, which cause severe headaches.
Are polarized sunglasses good for sports?
Polarized lenses are very popular among sports lovers, and are considered a ‘must-have’ for many fishermen and runners. Polarized lenses for sports glasses give you extra protection compared to standard sports eyewear. Polarized lenses reduce glare on reflective surfaces - like water or the road. In theory, this enables you to see objects and your surroundings clearer, sharper and unhindered. It allows fishermen to see straight through the water which is great for shallow water fishing.
Despite many benefits, polarized lenses for sports have some limitations too: Regretfully, polarized lenses can, in some cases, distort vision. Like when looking through a car window or windshield, one may see strange patterns created due to glass tempering. Similarly, in some specific instances, they may distort vision by showing unusual patterns (on the road) when biking or driving in harsh sunlight. What’s more, by taking away glare, polarized lenses also take away the ability of many sports people to correctly distinguish depth and contrast. In golf, players need the glare from the blades of grass to see slopes and judge the greens better.
Do polarized sunglasses make driving safer?
Driving sunglasses with polarized lenses can eliminate glare and will help keep your vision sharp while operating a motor vehicle, bicycle, or boat in difficult lighting conditions. However, as mentioned above, polarized sunglasses may distort your vision, and when you need to pay special attention to landmarks, wearing polarized sunglasses may require caution.
