Polarized v. Non-Polarized Sunglasses: What’s the Difference?

When buying sunglasses, you may have noticed that some glasses are labeled as “polarized,” and some are labeled as “non-polarized.” What are polarized sunglasses? What are non-polarized sunglasses? What is the difference between the two, and why should you care? In this article, we will explore the differences between these two types of sunglasses and the pros and cons of each. Once you know the ins and outs of these types of sunglasses, you’ll be able to make an informed decision about the pair that is right for you. If you’re looking to buy a new pair of sunglasses, you’re in the right place.

UVA, UVB, and UVC Rays

UVA (ultraviolet A) rays are longer wavelength rays that reach the Earth’s surface with less intensity than shorter wavelength UVB (ultraviolet B) and UVC (ultraviolet C) rays but are more pervasive and can penetrate clouds and windows. UVB rays have a shorter wavelength and higher intensity than UVA rays, while UVC rays have the shortest wavelength and highest intensity but are absorbed by the Earth’s ozone layer before they can reach us.

UV radiation from all sources can damage our eyes by causing eye strain, long-term vision problems such as cataracts, and even skin cancers around our eyes if they are exposed to unprotected sunlight for an extended time.

Polarized Lenses

Polarized lenses are specialized sunglass lenses designed to reduce glare from reflected surfaces such as water or snow. These lenses work by using a special coating that filters light waves horizontally, blocking out certain wavelengths while allowing others to pass through, which results in decreased glare.

Benefits of Polarized Lenses

Reduced Glare

The most significant benefit of polarized sunglasses is their ability to reduce glare from reflected surfaces such as water or snow. This feature makes them ideal for activities like fishing or skiing, where reflected light can be particularly intense and cause discomfort or distraction due to glare.

Improved Visual Comfort

Another benefit of polarized lenses is improved visual comfort since they can reduce eye strain caused by bright light reflection or bright sunlight conditions. They can do this while allowing sufficient light transmission for normal vision needs.

Increased Color Perception

Polarized lenses enhance colors by reducing reflective glare, which helps to increase our perception of colors that would otherwise be dulled due to glare and reflection from the environment.

Non-polarized Lenses

Non-polarized lenses do not have any filtering properties like polarized lenses, so they allow all light waves to pass through the lens for better clarity. Brightness levels are higher due to reflection from the environment when outside in direct sunlight conditions.

Benefits of Non-polarized Lenses

Increased Clarity

Non-polarized lenses offer superior clarity since they do not block out any light waves. All wavelengths pass through, providing brighter images with better contrast levels, especially in low-light situations such as indoors or at night.

Cost-effective

Non-polarized lenses can also be more cost-effective since they do not require specialized materials or coatings, resulting in cheaper manufacturing costs. This price difference makes them more accessible to a wide range of consumers who may not be willing or able to invest in higher-priced polarized lenses.

Conclusion

When it comes to choosing between polarized and non-polarized sunglasses, it’s critical to consider factors such as activity, environment, and budget before making a decision. Both options have their pros and cons. The most important thing is to always protect yourself and your eyes if you plan to be outside for an extended time.
