The Difference Between Polarized and Non Polarized Sunglasses

Must read

Non polarized sunglasses still protect your eyes from UV rays, but they don’t reduce glare as well. You can test this by looking through a pair of sunglasses that claim to be polarized and then looking at an LCD screen. If the screen darkens, then the lenses are polarized.

This is one of the best ways to determine if a pair of polarized sunglasses is worth the investment. Read on to learn more about polarized sunglasses.


Regardless of what you’re doing, it’s important to protect your eyes. Sunglasses not only look good and offer comfort, they also filter out harmful ultraviolet (UV) rays that can cause eye problems like cataracts, glaucoma, and age-related macular degeneration. Sunglasses are available in a wide variety of styles and colors, but they can be broken down into two distinct types: polarized and non-polarized lenses.

The difference between polarized and non-polarized sunglasses comes down to the way they deal with glare. Polarized lenses contain a special chemical that absorbs horizontally oriented light waves while allowing vertical ones to pass through. This process makes the sunglasses less reflective, which reduces glare on water, snow, and other surfaces. They may also have a coating that enhances color contrast and improves visual clarity in bright outdoor settings.

On the other hand, non-polarized lenses aren’t designed to eliminate glare caused by reflective surfaces. This can make them harder to see in situations where there’s a lot of reflected sunlight, such as when walking along a sandy beach or standing by a lake. However, they can be helpful for activities like driving on icy roads or flying an airplane because the lack of glare can help you spot patches of ice that would otherwise be difficult to see.

The main advantage of non-polarized sunglasses is that they’re usually cheaper to produce and manufacture than polarized pairs. However, there are plenty of cases where polarized sunglasses are worth the extra cost, especially if you spend a lot of time outdoors and want to minimize glare. Polarized lenses are particularly beneficial for activities such as fishing, skiing, and other water sports, where you need to see past surface reflections on the water or snow to catch fish or ski down a mountain. They can even improve the quality of your eyesight when viewing LCD screens, such as those on cell phones, computers, and electronic cash registers. The good news is that both polarized and non-polarized lenses can provide you with UV protection and offer great style, comfort, and clarity. So choose the lens that best suits your needs and enjoy your next adventure!


Many sunglasses come with polarized lenses, but they are also available with non-polarized lens options. Non-polarized lenses treat all sunlight equally and reduce the overall intensity to prevent eye strain, even in bright sunlight. They can still protect your eyes from harmful UV rays, and they are a good choice for anyone who wants to enjoy outdoor activities with the benefit of clearer vision. They are typically darker than polarized sunglasses, however, which can make them less easy to read LCD or LED screens on smartphones and tablets, and they may not be as comfortable for long periods of time.

In contrast, polarized lenses work to filter out horizontal light waves that create glare. They are often preferred by anglers, boaters, swimmers, golfers and runners who need a bit more help seeing through the reflections of water, roads and flat surfaces such as car hoods. Polarized sunglasses also enhance color, increase contrast and improve performance, but they can cause problems for some people. For example, they are not good for night driving because they can interfere with road signs and headlights. They can also make it difficult to see LCD and LED screens on devices like phones and tablets, although newer polarized glasses are improving this.

Non-polarized lenses don’t necessarily have to cost more than polarized versions, and they are usually a better choice for everyday wear. A number of sunglasses are offered with both polarized and non-polarized lenses in different frame styles and colours, and the difference in price is often negligible. Frame materials and brand name can also influence costs.

Felix Gray offers several frames in both polarized and non-polarized lens options, including our popular “Driftwood” model. The frames are made from hand-carved and sustainably sourced wood, which is lightweight and durable. The sunglasses are fitted with a high-quality anti-reflective coating on both the front and back sides of the lenses to prevent glare, and they feature spring hinges that allow them to fold flat for storage in a pocket or purse. The frames are designed to fit most face shapes and can be adjusted by a professional optician for optimal comfort.

Light Blocking

The lenses of a pair of sunglasses have a direct impact on the color and clarity of your view. Polarized lenses minimize color distortion and are ideal for outdoor enthusiasts who spend a lot of time outdoors or in sunlight. However, they do not reduce the intensity of reflected light from flat surfaces like roads, water, or car hoods and may cause eye strain when used in these situations. Non polarized lenses are an excellent choice for activities such as hiking or sitting by the pool, where you don’t need to worry about glare.

A polarized lens has a chemical coating that blocks horizontal rays of light while letting vertical ones pass through. This helps protect your eyes against glare that can distract you or even put your life in danger.

Polarized lenses are very popular among fishermen and people who spend a lot of time on the water. They also help eliminate glare that can be caused by sun’s reflection off of the water or snow. These lenses are especially useful in bright, sunny weather when glare can be problematic and dangerous.

However, polarized lenses can make it difficult to see LCD screens on devices such as smartphones and tablets. This can be a problem if you use these devices to check your GPS while hiking, or when you’re on the road and need to read maps. It can also be a problem when using a computer or tablet in a bright room. If you’re concerned about this issue, talk to your optometrist about getting a non polarized pair of sunglasses.

As an added bonus, non polarized lenses can offer UV protection as well. This is a big advantage over polarized sunglasses, which only offer UV protection on the front of the lenses. So, if you’re planning on spending a long day in the sun or going for a hike, a pair of non polarized sunglasses is an excellent choice. Just remember that they won’t reduce glare as effectively as polarized sunglasses and may not enhance colors as well. So, it’s important to consider your specific needs and activities when choosing between polarized and non polarized lenses.


Polarized sunglasses are lenses that have a special filter that reduces the glare caused by reflective surfaces such as snow and water. They work like the vertical slats in a fence or tightly packed bars on a window, only allowing vertical light to pass through while blocking horizontal light (also known as glare). This feature makes them ideal for outdoor activities such as fishing and boating where reflected sunlight is a common nuisance.

Polarised sunglasses also help to cut down on glare from the sun, and can enhance colors, increase contrast and improve clarity. They can even protect against eye strain and are often recommended for people who have sensitivity to light or who have had cataract surgery.

There are a few things to keep in mind when considering polarized sunglasses, however. First, polarized lenses tend to be more expensive than non-polarized glasses. They also don’t always provide full UV protection unless they are explicitly labeled as such. Additionally, some polarized lenses can make it difficult to read screens on phones, tablets, and computers.

While there are definitely some benefits to using polarized sunglasses, there are also reasons not to bother with them. For one thing, polarized lenses can sometimes make it hard to see the color of an object, which can be a problem when trying to navigate on a clear day while hiking or sailing.

Another concern is that polarized lenses can make it harder to differentiate between colors, making them less effective in situations where precise vision is necessary, such as when driving on a sunny day. Finally, polarized sunglasses can sometimes cause halos around the edges of objects, which can be problematic if you’re wearing them for cycling or running.

Ultimately, the choice between polarized and non-polarized sunglasses comes down to what kind of activities you plan on doing in bright conditions. If you spend a lot of time outdoors or by bodies of water, it’s worth the extra cost to invest in a pair of polarized sunglasses. Not only will they help you to see better, but they’ll also protect your eyes from harmful UV rays and reduce annoying glare that can lead to eye strain and headaches.
