The Science Behind Polarized Sunglasses

February 27, 2023

Polarized sunglasses are a must-have accessory for anyone who spends a lot of time outdoors. Whether you're fishing, skiing, boating, or just enjoying a day at the beach, these can help reduce glare, improve color contrast, and protect your eyes from harmful UV rays. In this article, we'll take a closer look at the science behind polarized sunglasses, the benefits they offer, and the different types of lenses available.

What are Polarized Sunglasses?

Polarized sunglasses are a type of eyewear that has a special polarizing filter embedded in the lenses. This filter helps to block out reflected light, reducing glare and improving visibility. Unlike regular sunglasses, which only darken the lenses, these sunglasses work by filtering out specific wavelengths of light that cause glare, such as light reflecting off of water, snow, or pavement.

How Do Polarized Sunglasses Work?

It works by blocking out horizontal light waves. When light reflects off of a flat surface, such as water or snow, it becomes polarized, and the waves align horizontally. This creates a blinding glare that can be difficult to see through, especially in bright sunlight. They use a special polarizing filter that blocks out these horizontally aligned waves, allowing only vertically aligned waves to pass through. This helps to reduce glare and improve visibility, making it easier to see objects and details in bright, reflective conditions.

Benefits of Polarized Sunglasses

Polarized sunglasses offer a number of benefits, including:
  • Reducing Glare: This makes them a popular choice for outdoor activities like fishing, boating, and skiing, where glare can make it difficult to see clearly.
  • Improving Color Contrast: Polarized sunglasses can also improve color contrast and make colors appear more vibrant and true to life. This is because the polarizing filter blocks out certain wavelengths of light that can cause colors to appear washed out or dull.
  • Enhancing Visual Clarity And Sharpness: By reducing glare and improving color contrast, polarized sunglasses can help you see more clearly and sharply in bright, reflective conditions. This can be especially helpful when driving or participating in outdoor sports.
  • Protecting Eyes From Harmful UV Rays: Just like regular sunglasses, polarized sunglasses can help protect your eyes from harmful UV rays. Overexposure to UV radiation can lead to a variety of eye problems, including cataracts, macular degeneration, and even skin cancer around the eyelids.

Applications of Polarized Sunglasses

Polarized sunglasses are useful in a wide range of outdoor activities, including:
  • Fishing: Polarized sunglasses are a must-have for anyone who loves to fish. By reducing glare and improving visibility in the water, polarized sunglasses can help you spot fish and underwater obstacles more easily.
  • Skiing And Snowboarding: These can also be helpful for winter sports like skiing and snowboarding. They can improve visibility and make it easier to see obstacles on the slopes.
  • Boating: Boaters and sailors often rely on polarized sunglasses to reduce glare on the water and improve visibility. This can be especially important in situations where visibility is limited, such as in fog or low-light conditions.
  • Driving: These help drivers reduce glare from other cars and reflective surfaces on the road. This can improve visibility and reduce eye strain, making driving safer and more comfortable.

How Are Polarized Sunglasses Made?

The lenses are made by sandwiching a polarizing film between two layers of glass, plastic, or other materials. This polarizing film is made up of molecules that are oriented in a specific direction, and it is designed to block out horizontally polarized light waves. When this film is embedded in the lens, it creates a filter that only allows vertically polarized light to pass through.
There are several types of polarized lenses available, each with its own benefits and drawbacks. Here are a few of the most common types:
  • TAC (Triacetate) Lenses: TAC lenses are a popular choice for polarized sunglasses because they are lightweight, durable, and relatively inexpensive. They are also resistant to impact and scratch damage, making them a good choice for outdoor activities.
  • Glass Genses: They are heavier and more fragile than TAC lenses, but they offer superior optical clarity and scratch resistance. They are also less likely to distort vision or create optical aberrations.
  • Polycarbonate Lenses: Polycarbonate lenses, on the other hand, are lightweight, impact-resistant, and offer good optical clarity. They are often used in sports eyewear and other types of activewear because of their durability.

Retro Polarized Sunglasses

If you're looking for a classic, timeless style, consider retro polarized sunglasses. These sunglasses feature classic designs from the 1950s, 60s, and 70s, with modern polarized lenses for improved visibility and eye protection. Retro styles often feature oversized frames, bold colors, and unique detailing, making them a popular choice for fashion-conscious outdoor enthusiasts.
Polarized sunglasses are a great investment for anyone who spends a lot of time outdoors. By reducing glare, improving color contrast, and protecting your eyes from UV rays, they can make outdoor activities more enjoyable and safer. When choosing these sunglasses, consider factors like polarization efficiency, lens color, and frame design to ensure you get the best fit and performance for your needs. Whether you're fishing, skiing, boating, or just enjoying a day in the sun, polarized sunglasses are a must-have accessory for any outdoor adventurer.
