Polarized sunglasses have become a popular accessory for people who spend time outdoors. They are designed to reduce glare and improve visual clarity, making them ideal for activities such as driving, fishing, and skiing. But what exactly happens when you wear polarized sunglasses? While polarized sunglasses offer many benefits, they are not without their drawbacks. Some people find that they can make it difficult to see certain types of digital displays, such as those on smartphones and GPS devices. Additionally, they may not be suitable for certain activities, such as downhill skiing, where it is important to be able to see changes in the texture of the snow.

What are Polarized Sunglasses?

Polarized sunglasses are a type of eyewear designed to reduce glare and improve visual clarity. They are especially useful for outdoor activities such as driving, fishing, and skiing, where glare from reflective surfaces can be distracting and potentially dangerous.

Polarized lenses contain a special chemical that filters out light waves that are oriented in a particular direction, known as polarization. This helps to reduce glare from surfaces such as water, snow, and glass, which can reflect light in a way that causes visual discomfort and reduces visibility.

Polarized sunglasses come in both prescription and non-prescription options, and are available in a variety of lens materials including glass and plastic. They can also be combined with other lens features such as UV protection and anti-reflective coatings.

Overall, polarized sunglasses are a great choice for anyone looking to improve their visual comfort and clarity in bright outdoor conditions.

How Polarized Sunglasses Work

Polarized sunglasses have a special filter that blocks out certain types of light waves, reducing glare and improving clarity. They are particularly useful for outdoor activities like driving, fishing, and skiing, where glare can be a major problem.

The filter in polarized sunglasses is made up of molecules that are aligned in a specific way. When light waves hit the filter, they are absorbed or reflected depending on their orientation. Horizontal light waves, which are the ones that cause glare, are absorbed by the filter, while vertical waves are allowed to pass through.

This is because the molecules in the filter are aligned vertically, so they only allow light waves that are aligned in the same direction to pass through. This reduces the amount of reflected light that enters your eyes, making it easier to see clearly.

Polarized sunglasses are particularly effective at reducing glare from water, snow, and other reflective surfaces. They can also help to reduce eye strain and fatigue, as your eyes don't have to work as hard to filter out unwanted light.

Benefits of Wearing Polarized Sunglasses

Polarized sunglasses have become increasingly popular in recent years, and for good reason. They offer a range of benefits that make them a great investment for anyone who spends time outdoors. In this section, we'll take a closer look at some of the key benefits of wearing polarized sunglasses.

Glare Reduction

One of the primary benefits of polarized sunglasses is their ability to reduce glare. Glare is caused by light reflecting off surfaces like water, snow, and pavement. When this light enters your eyes, it can cause discomfort and even temporary blindness. Polarized lenses are designed to block this reflected light, reducing glare and improving visual comfort.

Increased Contrast and Clearer Vision

Another benefit of polarized sunglasses is that they can increase contrast and provide clearer vision. By blocking out glare, polarized lenses allow you to see details more clearly, even in bright sunlight. This can be especially helpful when driving, boating, or engaging in outdoor sports like golfing, skiing, or sailing.

UV Protection

Polarized sunglasses also provide protection from harmful UV rays. Exposure to UV radiation can cause a range of eye problems, including photokeratitis, cataracts, and even blindness. Polarized lenses block both UVA and UVB rays, helping to keep your eyes safe and healthy.

Reduced Eye Strain and Fatigue

Wearing Polarized sunglasses can also reduce eye strain and fatigue, especially when using digital screens like smartphones or LCD screens. The glare from these screens can cause discomfort and even headaches, but polarized lenses can help to reduce this effect.

Drawbacks of Wearing Polarized Sunglasses

One of the drawbacks of wearing polarized sunglasses is that they can cause a dimming effect. The polarizing filter in the lenses reduces the amount of light that comes through, which can make your surroundings look darker. This can be especially problematic in low-light conditions, such as when driving at night or in a dimly lit room.

Uneven Surface Perception

Another potential issue with polarized sunglasses is that they can affect your perception of uneven surfaces. This is because the polarization filter can cause light to reflect differently off of surfaces, making them appear distorted or uneven. This can be particularly problematic when skiing or engaging in other activities where depth perception is important.

Disadvantages for Certain Activities

While polarized sunglasses can be beneficial for reducing glare and improving visibility in certain situations, they may not be the best choice for all activities. For example, polarized lenses can make it difficult to see LCD screens or certain types of watches. They can also make it harder to see rainbows, which can be a drawback for some people.

Additionally, polarized sunglasses may not be the best choice for daytime driving, as they can make it harder to see other cars' headlights. However, they can be helpful for reducing glare from the sun and improving visibility on bright, sunny days.

Overall, while polarized sunglasses can be a useful tool for reducing glare and improving visibility in certain situations, they do have some potential drawbacks that should be taken into consideration before purchasing a pair.

Choosing High-Quality Polarized Sunglasses

When choosing polarized sunglasses, it's important to select high-quality ones that will provide the best protection and clarity. Here are some factors to consider:

Anti-Reflective Coating

High-quality polarized sunglasses should have an anti-reflective coating to reduce glare and improve visual clarity. This coating helps to reduce eye strain and makes it easier to see in bright conditions. Look for sunglasses that have a multi-layered coating for maximum effectiveness.

Prescription Lenses

If you wear prescription glasses, you can still enjoy the benefits of polarized sunglasses. Many optical stores offer polarized lenses for prescription glasses. It's important to get your glasses from a reputable store that uses high-quality materials and has experienced opticians.

Special Chemical Film

Some high-quality polarized sunglasses have a special chemical film that enhances the polarization effect. This film helps to reduce glare and provide clearer vision in bright conditions. Oakley is known for using this technology in their sunglasses.

When shopping for polarized sunglasses, look for these features to ensure that you are getting a high-quality product. Don't be afraid to ask questions and do your research to find the best sunglasses for your needs.


Wearing polarized sunglasses can greatly benefit your eyes and overall vision. By reducing glare and improving contrast, polarized sunglasses can make outdoor activities such as driving, fishing, and skiing much safer and more enjoyable. Overall, polarized sunglasses are a great investment for anyone who spends a lot of time outdoors. Just be sure to choose a pair that is appropriate for your needs and activities, and always consult with an eye care professional if you have any concerns or questions.
